Latest News (15/04/2023) - Thunderbird 115 Compatibility

I am currently working on fundamental changes for Thunderbird 115 which first was release on July 11th and has a completely new user interface "Supernova". This required considerable work of rewriting all elements interacting with the main page (3pane) of Thunderbird (toolbar buttons, menus, folder tree) - this also includes drag and drop.

In my estimation, this work will take around 2 man-months. So it is very important that this effort is funded via my Add-on licenses. There are 2 license levels - please read the comparison chart to see which additional functions you get depending on your license. To download preview versions for Thunderbird betas or be informed about ongoing development on the new branch please leave feedback (or click the emoji button) at the Github issue 351. I am also discussing necessary changes to the UI, so please have your say there.

Thunderbird 115 is using the same system for permissions as the previous versions, and QuickFolders still has to use experimental APIs to achieve its full functionality. So you will see a message asking for full permissions. There is an article on Mozilla support explaining the detail.

In short: As Thunderbird follows Firefox which moves toward web extensions, a new technology has emerged that restricts Add-ons to use only managed entry points (APIs) for adding functionality - these are still largely incomplete as regards the many things Add-ons can actually add to the application. That's why Thunderbird allows using "experimental APIs", which is essentially a wrapper technology that allows (substantially modified) classic extensions to run on this system.

This also meant yet again splitting the code base for the older versions and having separate releases (it's not possible to combine both system in a single Add-on). Essentially new functionality will go into the newer versions of QuickFolders (6.0 and higher) whereas I back-port bug fixes and some selected functionality to the older versions of QuickFolders (5.15 and higher). Both versions will automatically update the correct user base as usual.

Thunderbird 68 support has ended on thunderbird.net

Unfortunately thunderbird.net does not accept updates for legacy versions anymore - they only support the new "Mail extension" format and our "mail extension with experimental APIs" which is a workaround for missing advanced features.

From of version 4.23 forward you have to install such legacy versions from the github releases page.

Major Features

Premium Feature: quickJump

A super quick way to find folders and Tabs by entering part of their name:

Click on the quickJump button (or use the configurable keyboard shortcut SHIFT+J in QuickFolders Pro):

A Search box opens where you can type a folder name and hit [Enter]. Or hit the [Down] key or mouse to select from the list of suggestions.

If exactly one matching folder is found Thunderbird will jump to it immediately. If multiple folders match a dropdown will show. Selecting the folder (or tab) name will jump to the folder.
Select Find Folder from the menu again if you want to hide the search box.

Premium Feature: quickMove

Uses the same button for moving mails to any folder:

Simply drag some mails up to the quickJump button (or use the configurable keyboard shortcut SHIFT+M in QuickFolders Pro), and then type the name of the target folder. The name is shown in red to indicate that mails are going to be moved. Note that you can gather mails multiple times and even from different folders - the mails won't be moved to the destination until you click on the suggestion on the search box.

Start typing to get relevant folder suggestions:

Clicking a folder name will move the dragged emails to the new destination and complete the quickMove operation.

You can also use this button for jumping to a folder by clicking it (quickJump).

To access child folders of any given folder use the key "/" - just enter the first characters of the parent folder followed by "/". This will additionally give you the option to create new subfolders before you move the mail.

The Escape key will hide the red box temporarily. You can right-click the button to display more options and the list of emails that are lined up for moving:

You can open the emails in a tab by clicking them.

Palette Types

It is now possible to select independent palettes for the different tab states selected » hover » dragover » uncolored.:

this way the signalling of important states (such as the current folder) can be made to stick out so it can be located much more easily.

Also the new architecture of palette options makes it easier to add different palettes in future versions.

Version Details

All dates are displayed in UK format: dd/mm/yyyy - you can request any version that is marked as not released or any old version listed; just send me a personal email from the quickfolders options dialog » on the Support tab - [(Jump to Screen Shot)].

  Improvements

  • Improved Italian Translations thanks to Leopoldo Saggin.
  • Localized hard coded English strings (thanks to Leopoldo Saggin for finding these)
  • New Feature: Mark Newsgroup Read [issue 458]

  • Accessibility Improvement: increased space around quickJump and reading list buttons to simplify dropping emails. Also added dotted lines around these during dropping / hovering. [issue 462]

    
  • Accessibility improvement: modify font size of category and find folder elements along with the font size of the tabs. [issue 461]

  • Updated tip for the alt+number keyboard shortcuts. You can use the tbkeys-lite Add-on in order to use ALT+Number shortcuts for navigation or to move emails to the first 10 tabs.

    
  • Opening support sites in a tab is now using API method - this helps future proofing the Add-on.

  Bug Fixes

  • Fixed layout issues in advanced tab settings
  • Ctrl+Right-click to open QuickFolders Commands didn't work anymore [issue 459]
  • Reading list: add current item to list not working [issue 455]
  • Paint Mode - brush icon too big [issue 457]
  • Fixed: quickMove error in conversation view when results are restricted to current mail account [issue 451]
  • Fixed: Advanced Search Settings - unchecking more multiple Accounts failed to save [issue 464]
  • Fixed in 6.5.1: Mark as Read (and similar commands) in Navigation bar may be applied to wrong folder [issue 467]
   

• Version 6.4.1 - 10/12/2023

  Version 6.4.0 was released on 03/12/2023

  Improvements

  • 6.4.1: Any tool menu item (such as support or license) now activates the correct settings page even when settings are displayed already.

  • Additional settings for QuickFolders are now accessible to all operating systems. These are now displayed with a little sprocket icon beside the main option, which can be used to get into advanced configuration.

    

    This makes the settings instantly more accessible without overloading the UI with too much information and having to build separate dialogs. Settings are opened as a filtered view of about:config (the search box is fixed so that the user cannot accidentally overwrite unwanted settings).

  • quickfilter search box does not loose focus 1 second after clicking a QuickFolders Tab [issue 434]

  Bug Fixes

  • You can now load configuration from the license tab, which was broken by Thunderbird 115. [issue 425]
  • When dragging emails across QuickFolders tabs, popup menus are now removed again. [issue 428]
  • Fixed a hanging subfolder menu on first tab when dragging mail to quickMove Button [issue 410]
  • Fixed disappearing context command to 'Customize Icon' in folder tree [issue 430]
  • You can now move folders using Shift-M again. [issue 436]
  • In advanced tab properties - setting to / from fields for folders is now working again [issue 437]
  • Fixed layout and visibility problems with transparency and unselectable items in tab-specific properties panel on Mac [issue 433]
  • Thunderbird 122 beta - cannot add new tabs to toolbar [issue 439]

  Other Improvements

  • Removed unwanted text shadow in quickJump help panel [issue 427]
 

• Version 6.3 - 20/10/2023

  Improvements

  • Added custom icons in folder tree in Thunderbird 115.

    These were supported in previous versions and QuickFolders will be able to load your previous settings if you used v5.17.1 or 5.18 on Thunderbird 102 or an earlier version. To display the menu right-click any folder in the folder tree. We use the official menus API, which only allows a single Add-on command that is automatically appended to the bottom of the folder pane menu. [issue 399]

    If the folder has no custom icon the command Customize Icon... will be shown:

    

    If the folder already has an icon there will be a choice of replacing or removing the icon in a QuickFolders popup menu.

    

    The maximum number of configurable icons is determined by license type. Icons should ideally be not bigger than 18*18px, you can get a bunch of examples from here.

  • Made registration screen less tall / easily resizable [issue 400]
  • Support svg icons in tabs - make icon size configurable. [issue 407]
  • French locale reviewed by Fx Benard Many thanks to for your work!

  Bug Fixes

  • Fixed: Open folder from QF Tab while viewing a message [issue 398]
  • Fixed toolbar issues in Single Message window: "null" element [issue 404]
  • Navigation Bar: Avoid horizontal overflow in columns view [issue 409]
  • Tab specific properties panel was cut off at bottom [issue 408]
  • Fixed: "Empty Junk" command intermittently hidden from context menus [issue 406]
  • Dragging mail to Current Folder tab does not open subfolders popup [issue 412]
  • Message list scrolls to top when switching folders [issue 417]
  • Drag to new subfolder command was missing when dragging mail to a QuickFolders Tab [issue 420]
 

• Version 6.2 - 30/08/2023

  Improvements

  • The menu font size can now be changed - this is now independent of the button label for all popup menus. [issue 394]

    

    This may be done so that more subfolders can be fit in the popup menu:
    

  • You can now also change the font size of the folder tabs in 'Apple Pills' theme.

  • Folder menus now support Thunderbird compact density - this will be helpful for tabs with many subfolders. [issue 396]

    In Thunderbird115, Density can be set directly in the Application menu:

    
  • Improved coloring and layout for Apple theme.
  • Display localized license expiry date in registration dialog (not as YYYY-MM-DD).

  Bug Fixes

  • Fixed: quickJump switched to matching single mail tab instead of jumping to Folder in current tab. [issue 389]
  • Fixed navigation bar (current folder bar) positioning when switching between classic and vertical layout. [issue 395]
  • Also made sure that current folder tab layout is changed when a different theme is selected.
  • Fixed: quickFilters Filter assistant mode is not detected when configured to automatically start with Thunderbird [issue 397]
  • Fixed: Keyboard collision with quick filter toolbar; typing [Shift]+[F] and [Shift]+[M] in the search bar triggered the quickJump search. [issue 392]
  • Number shortcuts not working - move mail with Option+Shift+Number (Note that ALT shortcuts are already taken by Thunderbird, so we need to use CTRL (Windows, Linux) or OPTION (Apple) as modifier to activate tabs. [issue 387]
  • Repaired: set keyboard focus back to thread pane after quickmove.
  • QuickFolders did not detect if quickFilters assistant started automatically. This is now working even if quickFilters gets restarted from extension manager. [issue 397]

  Miscellaneus

  • Retired option to set QuickFolders toolbar position. [issue 380]
  • After the license was viewed via the menu "check license status", now the "renew license" button is reset for the session and returned to standard toolbar appearance (special coloring / message is removed)
  • Skip to next unread folder - this still needs some fixing as it may skip unread mails in the next unread folder. We are looking for a replacement function for something that isn't accessible in Thunderbird 115 anymore.
   

• Version 6.1.1 - 09/08/2023

  Improvements

  • Tabs for unified folders (such as Unified Inbox) now support showing the actual folders, renamed to their account names.

    
  • Redesigned menu icons and fixed a number of issues in the options screen - icons had some problems changing to dark themes. If you experience missing colors in QuickFolders settings, you can enable the about:config setting svg.context-properties.content.enabled = true
  • Added internal configuration Option to close tab after mail is moved from single message view. To activate the new option, set extensions.quickfolders.quickMove.singleTab.autoClose in configuration database. [issue 375]
  • Moved F9 keyboard shortcut to toggle folder pane to F10, as F9 was reserved by Thunderbird. This can be changed from the Add-ons Manager via the tools menu.

  Bug Fixes

  • Fixed: Create new subfolder while dragging to tab throws error.
  • Fixed: quickJump shortcut = to show most recent used folders broken.
  • Bookmarks: in Thunderbird 115 "Add current item" was not working [issue 376]
  • You can once again use the filter assistant to create filter rules with quickMove. [issue 385]
  • Fixed the color picker for custom colors in current folder toolbar.
  • Fixed: Changing 'minimum height' opens help topic instead. [issue 372]
  • Fixed: Custom navigation bar icon color picker doesn't work and could lead to unreadable current folder button. [issue 383]
  • Corrected the reported number of messages moved when using quickMove. [issue 354]
  • Fixed in 6.1.1: Toggle toolbar button and toggle folder pane only work after install, not next session [issue 386]

  Known Issues

  • Skip to next unread folder button - this still needs some fixing as it may skip unread mails in the next unread folder. We are looking for a replacement function for "jump to first message" - something that isn't accessible to the Add-on Code in Thunderbird 115 anymore.

  • New CSS rules for folder tree icons: as the folder tree has been rewritten as HTML list, we cannot use the foldertreeitem.getProperties function to store this information anymore.

    Instead we need an new method to store this information separately - and then rules for styling the folders have to be recreated. This may take a little while.

    In the meantime, QuickFolders 5.17.1 has implemented an automatic backup routine for custom icons.

    In that version, when starting up, QuickFolders automatically backs up custom icons on the folder tree. Future versions of QuickFolders 6.* may use this data to restore the tree layout and load those icons back. So if you have ran 5.17.1 before, then your icon information likely has been stored into a separate file, so it can be recovered later!

 

• Version 6.0 - 29/07/2023

  I am currently working on the conversion of the QuickFolders Addon for the new Thunderbird User Interface 'Supernova'. This has been implemented in the next major version of Thunderbird 115, which is planned to go public in July 2023. It required considerable work of rewriting all elements interacting with the main page (3pane) of Thunderbird (toolbar buttons, menus, folder tree).

  You can read up on the current progress of this work here: issue 351 This work is exclusively funded by the sale of license so if you are interested in using QuickFolders in the future, please consider buying a license or renewing your license. Unlike a Windows Application, frequent work on the code of experimental Add-ons like QuickFolders is inevitable. I have kept this project alive for 14 years now and I would like to continue doing so in the future. Thank you for your kind attention.

  Functionality converted to Thunderbird 115

  • Rewritten QuickFolders toolbar to show in a different element (SuperNove wants all buttons displayed in their new Unified toolbar). All Folder menus remain as xul items for now as they are difficult to recreate in HTML. The new main styling including custom icons in the QuickFolders tab has been implemented.

  • Following the Firefox model, Thunderbird 115 allows only one single action button (I am currently negotiating with the thunderbird team to allow more optional buttons) I decided to add the toolbar toggle button to the unified toolbar. With this the QuickFolders toolbar can be hidden temporarily:

    

    When you install QuickFolders in Tb115 for the first time, all Add-on buttons are added on the top right - you may move it by right-clicking the unified toolbar and selecting customize:

    
  • Recent Folders had to be rewritten.
  • Drag & Drop was broken and had to be fixed.
  • Rewritten the event listeners in folder tree (drag and drop)
  • The Navigation toolbar (a.k.a. Current Folder Bar) in center screen had to be reimplemented because there are now multiple 3pane documents » windows (one for each Thunderbird tab) Also I am now hiding unneccessary elements of the toolbar when it is displayed in the single message tab or single message window.
  • Implemented main toolbar buttons (Show QuickFolders toolbar) as Unified toolbar action button. Unfortunately
  • Storage of QuickFolders category per tab is now implemented with the new tab sessions API.
  • Most of the icons in the options window have been redesigned as svg graphics for a modernized look and feel. Also, dark theme support has been improved.

  Issues » Open Points

  • New CSS rules for folder tree icons: as the folder tree has been rewritten as HTML list, we cannot use the foldertreeitem.getProperties function to store this information anymore. Instead we need an new method to store this information separately - and then rules for styling the folders have to be recreated. This may take a little while - I am considering writing a tool to extract the information from older versions of Thunderbird (91 or 102) so they can be migrated to 115 later.
  • Toolbar buttons Create folder, Skip Folder can currently not be added (because the mail toolbar is gone and unified toolbar only allows noe single button per Add-on)
  • When a QuickFolders Tab is selected, Thunderbird still needs to scroll the folder tree to that folder.
 

• Version 5.18 - 27/08/2023

  Improvements

  • The menu font size can now be changed - this is now independent of the button label for all popup menus. [issue 394]

    
  • You can now also change the font size of the folder tabs in 'Apple Pills' theme.

  • Folder menus now support Thunderbird compact density - this will be helpful for tabs with many subfolders. [issue 396]

    In Thunderbird 102, density can be set from the View menu:

    
  • Improved coloring and layout for Apple theme.
  • Display localized license expiry date in registration dialog (not as YYYY-MM-DD).
   

• Version 5.17.1 - 07/08/2023

  Improvements

  • Tabs for unified folders (such as Unified Inbox) now support showing the actual folders, renamed to their account names:

    
  • Redesigned menu icons and fixed a number of issues in the options screen - icons had some problems changing to dark themes. If you experience missing colors in QuickFolders settings, you can enable the about:config setting svg.context-properties.content.enabled = true
  • Automatically back up the custom folder icons for future restauration in Thunderbird 115.

    On startup, QuickFolders will automatically backup custom icons on the folder tree (all folder URLs and the locations of their icons) in the file quickFolders-FolderTree.json which will be stored in the profile/extensions folder. This will be only done once automatically.

    The backup function can be also invoked manually via the QuickFolders debug menu - to access this, click on QuickFolders tools button while holding down SHIFT, and then select Debug » Backup folder tree icons [issue 384]

    

  Bug Fixes

  • Fixed the color picker for custom colors in current folder toolbar.
  • Fixed: Changing 'minimum height' opens help topic instead. [issue 372]
  • Fixed: Custom navigation bar icon color picker doesn't work and could lead to unreadable current folder button. [issue 383]
   

• Version 5.16.1 - 23/04/2023

  Improvements

  • QuickFolders now warns about license expiry 10 days beforehand. [issue 350].

    

  • News button will not be shown unless at least minor version number of QuickFolders is increased. But you can always read up on the latest changes via the tools menu item "Latest Update News..." - and used to be titled "View Splash Screen".

    
  • Added pricing section to the buy license dialog. This explains that prices can be looked up via the browser without necessarily buying, by clicking the appropriate button on the screen.

  Bugs Fixed

  • Fixed "Compact Folder" on current folder submenu.
  • Corrected the Number of days left in license by rounding up.

  Maintenance Fixes 5.16.1

  • fixed Catalan locale (newsSection).
  • improved layout on Renew » Extend button
     

• Version 5.15.2 - 24/12/2022

  Maintenance Fixes

  • Version 5.15.2 (published 24/12/2022):

    The quickFilters assistant was triggered multiple times when dropping multiple mails to tab or multiple mails are moved using quickMove. This new version will move emails together, as long as they come from an identical source folder. This should prevent multiple assistant windows in the majority of use cases. [issue 335]

  • Version 5.15.1 (published 22/12/2022):

    A regression in v5.15 caused all text in popup menus (subfolders » commands) to appear missing for most users. This was because of the default size of 0 being falsely applied as a literal value. [issue 333]

  Improvements

  • [issue 329] Fixed inconsistent menu font size when dragging mail to a subfolders of a QuickFolder
  • [issue 315] Removed the term 'Orphaned Tabs' in all User Interface texts
  • Modifications to internal code for triggering the quickFilters filter assistant to avoid "monkey patching" (overwriting) Thunderbird internal functions. These changes are needed from the next version of quickFilters (5.7 and higher) onwards to avoid duplicate prompts for filter creation.

  Bugs Fixed

  • [issue 328] Fixed: Using quickMove to move emails from different source folders didn't remove them from the menu
 

• Version 5.14 - 14/11/2022

  Improvements

  • You can now set the icon color on the current folder with the custom background. This can be used to address coloring problems with third party Thunderbird themes. [issue 317].

    

  • New Function for QuickFolders Pro users to mark folder as read and jump to next unread folder. [issue 320] Hold down CTRL while clicking on the button "Mark Conversation as Read and jump to the next unread Email":

    

  Bugs Fixed

  • Fixed: The Compact Headers Add-on painted over icons in Current Folder toolbar. [issue 314]
  • Fixed a problem with missing quickFilters buttons on Current Folder toolbar. This requires quickFilters to be updated to version 5.6. [issue 316]
  • Fixed: Tabs for Unified folders can falsely be reported as invalid, unless Unified folders are currently visible in folder tree. [issue 322]
     

• Version 5.13.1 - 28/09/2022

  Maintenance Fixes

  • [issue 312] Fixed in 5.13.1: When moving an email to a submenu via the popup folder that shows direct child folders this can generate an empty duplicate without subject line.

  Improvements

  • [issue 306] New option to restore unread or force read status on messages when dragging them to QuickFolders.

    

  Bugs Fixed

  • [issue 308] quickFilters assistant will not fail anymore when moving mail to IMAP folders. Here is a video that describes the process of creating filter rules using the quickFilters assistant - this is to automate moving mail to your favorite folders.
    1. With the Add-on quickFilters installed, click on the button in the toolbar to activate its assistant.
       
    2. Drop an email to a QuickFolders tab (or use the quickMove button).
    3. The quickFilters assistant will show up and give you a choice for creating rules to automatically move similar mails.
       
  • [issue 309] quickFilters assistant will not fail anymore when moving mail to QuickFolders on IMAP. There used to be a problem with synchronisation while waiting for the IMAP server to complete the mail move operation.

  Improvements

  • [issue 292] Close quickJump box after using the = shortcut key (to display recent folders).
  • [issue 291] Update Thunderbird's "Move to Again" and "Copy to Again" menu items when moving or copying mail through a QuickFolders method.
  • [issue 296] Exchange account validation - you can now validate a license key even if the licensed email is configured for an Exchange account via 3rd party Add-ons such as Owl or Exquilla. This works from Thunderbird 98 forward.

  Bugs Fixed

  • [issue 297] When using the search box during quickMove » quickJump and looking for parent folders you can now enter composite names by typing the beginning of each word delimited by a space. For Example you can now enter "mu fl/" to list all subfolders of a folder "Munson-Fletcher". Valid delimiters of existing folder names are - _ @ + & . and space.

  Improvements

  • [issue 283] Fixed: Significant slowdown of Thunderbird 102 with QuickFolders

    There is some inefficiency in Thunderbird code for the folder tree which can be exacerbated by QuickFolders. I have removed as many function calls as possible without impacting on functionality. On startup some context menus have to be generated for efficient drag+drop; this is now postponed to a later stage to yield some processing time to the User Interface.

  Bugs Fixed

  • [issue 279] Fixed: Thunderbird 102 - current category is not remembered » selected; in this solution I store the current category of each tab (folder and messages) whenever a tab is opened » moved or closed. This information is only stored for the last Thunderbird window that is closed.
  • [issue 280] Customized folder tree icons stopped to work independently of QuickFolders tabs with icons. Custom icons are now back!
  • [issue 287] Fixed the removal of invalid (orphaned) tabs through the tool menu command "remove invalid tabs". Also renamed it for clarity: this used to be called "find orphaned tabs"

  Known Issues » Work in Progress

  • [issue 284] Recent folders menu doesn't show or takes a very long time in Thunderbird 102 - There is some inefficent code in Thunderbird 102 at the moment, so I have started to use their own internal function to generate this; I am hoping there will be some improvement added in Thunderbird itself in a later version and will remind the core team.
       

• Version 5.10.3 - 14/07/2022

  QuickFolders is now compatible with Thunderbird 102, the official new version for 2022 » 2023. To help fund this Add-on for the next year and the unavoidable changes necessary to switch over to an API based approach, please buy a QuickFolders Pro license

  Maintenance Version 5.10.3 - 14/07/2022

  • [issue 281] this maintenance version will be able to reconstruct tabs after upgrading from Thunderbird 91 to 102 even if the server and username have been modified due to bug 1573690. The previous version failed with reconstructing these on IMAP folders.

    To automatically rebuild (and avoiding invalid tabs) is only possible if 5.10.1 was previously run on an older profile (Thunderbird 91 or older)

    If you already upgraded to Thunderbird 102 previously and still have invalid tabs, you can follow the detailed instructions at the last comment on [issue 281]

  • [issue 283] Thunderbird 102 is severely slowing down compared to Thunderbird 91 with QuickFolders installed. I am currently working on a permanent solution - if you would like to test preview versions you can download them at the Github issue linked above.

  Maintenance Version 5.10.2 - 07/07/2022

  • [issue 281] 5.10.2 - this maintenance version will be able to reconstruct tabs after upgrading from Thunderbird 91 to 102 even if the server and username have been modified due to bug 1573690. To successfully reconstruct (and avoiding invalid tabs) is only possible if 5.10.1 was previously run on an older profile (Thunderbird 91 or older)

    If you already upgraded to Thunderbird 102 previously and experience invalid tabs, you can now generate troubleshooting information via right-click QuickFolders Commands » Tab Specific Properties... This will copy the assumed account and the (invalid) folder URI to the clipboard.
    

    For reference you can click on any real folder in the folder tree and then SHIFT+Click on the QuickFolders tool icon, then select Debug » Copy current folder info! This will copy the account and correct expected URI to the clipboard. By comparison of these data points it I can fix your folders through exporting the folder configuration and then text search+replace the differing URIs (or by simply inserting the correct account)
    

    Detailed instructions can be found at the bottom of: [issue 281]

  • Fixed the missing close [x] icon on the advanced tab properties panel, which was hidden by style changes in Thunderbird 102.
  • Fixed icon coloring for the tools and QuickFolders Command menus in dark mode (Thunderbird 102).

  Maintenance Version 5.10.1 - 05/07/2022

  • [issue 281] 5.10.1 - this maintenance fix stores the account id for every tab. When upgrading to Thunderbird 102, this can potentially rename the servers due to bug 1573690 - then the account can be used for reconstruction of invalid folders. I am currently working on code that can help in fixing this problem automatically.
  • Fixed icon spacings in folder popup menus in Tb102.

  Version 5.10 - 12/06/2022 - Thunderbird 102 Specific changes

  • Increasing maximum TB version for next ESR - Thunderbird 102.* is planned to be supported from now on. Also increased minimum version to 92.0 - because of new APIs 78 will not be supported with new features » bugfixes.
    If you consider updating to Thunderbird 102 please make a backup of your prefs.js - Thunderbird can potentially generate invalid tabs, and this can be repaired much more easily by knowing certain server settings that are stored in prefs.js preceding migration. See [issue 281] for detailed information!
  • [issue 272] Implemented new folder listener interface. The new version of Thunderbird implements a different folder listener interface. This meant a lot of functions (such as updating URLs when renaming folders and updating their connected tabs or updating unread counts on the tabs) were broken.
  • Fixed repair folder code.
  • Fixed support site links in Options Dialog.

  Improvements

  • [issue 263] If Preferences are open in inactive Tab, clicking the options button now activates it.
  • Added title to preferences tab

  Bugs Fixed

  • [issue 265] Reading list: If an email cannot be found due to an invalid » deleted folder, QuickFolders wasn't displaying the search dialog.
  • [issue 262] Fixed: Recent folders on Navigation Bar (Current folder toolbar) outdated when dragging emails
  • Fixed: support mail to... description in options dialog
  • [issue 268] Fixed: When clicking the Current Folder Bar, it showed an old list of subfolders

  Miscellaneous

  • Removed legacy settings dialog and associated menu item
  • Removed legacy code (supportsMap)

  Known Issues

  • [issue 281] Updating to Thunderbird 102 can generate invalid tabs - make sure to backup prefs.js before updating in order to correct this problem more easily. Some accounts in your profile may be affected, so it is a good idea to mitigate this problem.
   

• Version 5.9.1 - 05/04/2022

  5.9.1 - Maintenance Fixes - 05/April/2022

  This maintenance version will be released shortly.

  • Simplified recent folders menu behavior for keyboard navigation.

    [issue 254] The new [=] shortcut key of quickMove/quickJump showed an arrow to visit child folders, which meant that the folder itself could not be opened without mouse, which impeded the workflow.

    I have decided to instead not show subfolders for these recent folders as it doesn't add much value for what essentially should be a repeat operation. I have also extended this to the other recent folders menus (e.g. on the recent folders tab).

    One can still restore the old behavior (of showing subfolders) by setting the config setting extensions.quickfolders.recentfolders.subfolders = true. To do this you can open QuickFolders General Settings and right-click the Recent Folder Tabs checkbox:
    

  • [issue 252] Fixed: Tabs with invalid folder address can break search results. This can happen if you exclude accounts from the search after recreating a profile with different spelling.
  • [issue 255] Fixed: CTRL Right-clicking on the active folder can create multiple instances of the folder commands submenu.

  Improvements - 30/03/2022

  • [issue 241] using quickJump » quickMove via shortcut - hitting Enter will now always select the last successful location (even when the name is ambiguous) and not the top item of the menu. To use the first item of the menu using Enter the menu hast to be visible - either by starting to type or pressing arrow-down.
  • [issue 242]

    Use '=' key for recalling folders from recent quickMove » quickJump operations

    When using the quickMove or quickJump search box you can now access folders of its previous jump » move operations by typing "=" as the first character.

  • [issue 236] Convert options dialog to pure HTML. Amon other things, this fixes the color pickers that have stopped working on Mac. Long term, all Dialogs and User Interfaces need to be converted to HTML to become future proof and pure API based. There are still things that cannot be done with HTML right now (such as folder dropdowns that aren't cut off at the toolbar borders), so this is an ongoing effort for the predictable future.

  Bug Fixes - 30/03/2022

  • [issue 232] Fixed: When Adding a category to a tab, another category may be replaced
  • [issue 235] Fixed: quickJump may fail if "Compact mode" in folder tree is enabled.
  • [issue 220] Fixed an issue with license validation (alias identity support).
  • Fixed "change order" dialog.
       

• Version 5.8.3 - 03/11/2021

  Version 3.8.3 - Maintenance version - 03/11/2021

  • Fixed in page links for users with licenses! Before licensed users were directed to the top of a page instead of the correct location (such as the feature comparison list or current version info)
  • Improved speed of license validator for Thunderbird 91.2 and later.
  • Improved readability for menu items on (license-) restricted tabs.

  QuickFolders 5.8.2 - Maintenance Version - 21/10/2021

  • - [issue 5] [issue 67] [issue 77] [issue 105] Fixed: Long folders menu scroll issues - when the subfolders list of tabs were too long to fit on screen, dragged mail couldn't be dragged down into the clipped off list. The menu did not scroll down.

  Improvements - 5.8.1 - released 18/10/2021

  • [issue 205] When clicking "get Messages" from any tab, QuickFolders used to also jump into the folder. This behavior is actually not desired, as you may have filter rules defined which remove mail from the Inbox so jumping into the Inbox is not useful when new mail is downloaded.
    
  • [issue 191] Support large icon in QuickFolders toolbar buttons for high resolution displays.

  Bug Fixes + Miscellaneus - 5.8.1 - released 18/10/2021

  • [issue 211] Fixed: move Folders in quickMove fails in Thunderbird 91. You can now again drag (multiple) folders from the tree to the quickMove button in order to relocate them. Or use the Shortcut Shift+M if you have a QuickFolders Pro license.
  • [issue 209] Fixed: Tabs in Options Dialog became illegible in Thunderbird 91 when using dark themes with bright text.
    
  • [issue 203] Fixed: When the quickFilters Add-on activates its assistant, all icons on left to the tabs on the QuickFolders toolbar turned white.
  • Fixed: In Thunderbird 91, background area behind current folder toolbar does not show correct background color from lightweight theme, even when lightweight support is enabled.
  • Fixed: The History Tab was not displayed anymore when updating QuickFolders.
   

  Known unresolved issues » Work In Progress

  • [issue 204] WIP - Thunderbird 91: Background of QuickFolders toolbar doesn't support some themes when set to transparent
  • [issue 208] Upgrade from TB 78 to 91.1.2 sometimes leads to invalid » "orphaned" tabs. For the moment, you should be able to resolve these by clicking a tab with the "broom" » invalid icon or by running the tool command "Find Orphaned tabs.".
    Should this not give the desired results, then you can export your tabs via the license tab or on the Advanced tab using the [Copy Tabs] button and send me the file so I can help you fix this.
  • [issue 217] Tools Menu icons black in dark themes - Win10
     

• Version 5.7.2 - 04/09/2021

  QuickFolders 5.7.2 - Maintenance Version

  • Fixed in 5.7.2: When the quickFilters Add-ons activated its assistant, all QuickFolders icons on left to the tabs turned white.
  • Added max version (Thunderbird 91.*) as mandated by new policies on ATN.

  QuickFolders 5.7.1 - Maintenance Version - 28/08/2021

  • [issue 199] Fixed: when looking for parent folders using the syntax parent/parent/searchfolder, parent folders with name being only a single character long were not included.
  • [issue 197] Instructions on empty toolbar get duplicated on folder change.
  • Removed "workaround" experimental APIs (notifications, accounts)

  5.7 - released 10/08/2021 - Improvements and Important Changes

  • [issue 187] Implemented a QuickFolders Standard License. Apart from the unpaid version, there will be now two different licenses, QuickFolders Pro and Standard, and the unfunded version will have a number of restrictions. Most importantly, no more than 10 tabs are supported without any license. This is necessary in order to fund ongoing and future work so that the Add-on won't be lost to all users when Thunderbird moves away from experimental APIs. Standard Features will be listed here. Read the new comparison chart to see which functions you get depending on your license.

  • [issue 114] Make QuickFolders compatible with Thunderbird 91 (ESR 2021/22). This is the list of issues found and fixed so far:

    1. Fixed the missing (and badly styled) [Buy License] button at the bottom of the options dialog. this is done by loading a separate style sheet link element into the shadow DOM.
    2. Fixed: showing the debug settings (and other advanced settings) via a small window that filters "about:config" stopped working in Tb91.
    3. Fixed: missing icons on sliding notification bars
    4. Removed deprecated fixIterator constructs
    5. [issue 189] Fixed: No longer able to move a message by dropping it on a quick folder tab the function copyMessages was renamed in Tb91
    6. [issue 190] Fixed dragging the envelope from current folder toolbar (Navigation bar)
  • Simplified and improved splash screen.
  • [issue 184] Update Notice - [What's New] button was badly visible when using different QF theme than flat style.

  Bug Fixes + Miscellaneus

  • [issue 166] 3rd party themes - Current folder toolbar colors are incorrect until Refresh visible tabs command.
  • [issue 186] Theming make some items in options screens hard » impossible to see - improved visibility of dropdowns in options screen when using dark (and third party) themes.
  • [issue 185] On installation » sometimes restart or update of _other_ add-ons category is reset to "all".
  • Ongoing work of Rewriting code to use APIs instead of Thunderbird's internal functions see [issue 147] for up to date detail.
  • Removed obsolete rsa code module
  • Default event for popupmenus changed from click to command to better support keyboard only navigation. [extensions.quickfolders.debug.popupmenus.folderEventType]
           

• Version 5.6.6 - 11/07/2021

  Maintenance Items - 5.6.6

  • [issue 177] Fixed: Unreliable search if space and - characters are combined in the search string
  • [issue 174] Main QuickFolders toolbar was hidden in single message tabs by default. Changed to being visible by default and added a setting to QuickFolders General settings.
  • [issue 176] Hide instructions on how to set up QuickFolders at startup (for users who already have set up tabs)

  Improvements

  • [issue 155] Significant new search features have been added to the quickMove » quickJump function. For help on these, you can now click the [?] symbol to the right of the search field.
    

    Support entering multiple words in a search string to find longer folder names that are composited, such as "Fred.Flintstone" "Invoices June 2020" "Research+Development". These can now be found by entering the starting letters of the words within the folder name, in any order. e.g. "f f" "2020 inv" "Dev Res".
    

    The following characters are regarded as word boundaries and don't need to be typed: _ . - + & @
    

    This can also be combined with the parent folder syntax by entering the parent folder start followed by a forward slash /:
    

    The new character > can be used to skip any part within the path and if you do not know their order within the folder hierarchy.

  • When the search box is opened there is a new button to display a help panel:
    
    

  • The update Splash screen with the translated list of new features which used to be opened on update will from now on not be displayed automatically anymore. Instead there is a message on the QuickFolders button - click it once to read the latest news when you want.
    

    The splash screen can also be re-opened again from the tools menu:
    
    

  • Improved overall performance for typing by optimizing the keyboard listener that handles global shortcuts.

  • [web extension migration] Improved many functions that worked via accessing the "most recent Thunderbird window" and replaced them with event notifications that propagate to every window. This uses the Notification Tool library and the background script (a mechanism of the new API based "mail extensions" model).

    This way all Thunderbird windows (if you work from multiple windows) will be updated correctly when doing one of the following actions. All these now work simultaneously and update in multiple Thunderbird windows.

    • rename a tab
    • move a tab positionto a different position
    • delete a tab or remove it from or add it to a category
    • change the layout of all QuickFolders toolbar elements from the options dialog (themes, colors)
    • rename QuickFolders categories
    • change the theme » buttons of the Current Folder Bar
    • change options of where to display the Current Folder Bar (main window, message tab, single message window)
    • changes to the license when entered » validated
    • unlocking features such as the advanced » tab-specific properties when a license key is entered

  Bug Fixes + Miscellaneus

  • [issue 172] Fixed (in v5.6.5): quickMove result paths are only showing last 2 folders in path when only a single search word is entered.
  • [issue 150] Unwanted new line characters "\n" were displayed in some strings in version 5.5.2
  • [issue 167] Fixed: Unreadable colors of QuickFolders toolbar font and Navigation bar icons in Linux.
    
    
  • Added instruction text on empty toolbar which was missing since Thunderbird 78 migration:
  • [web extension migration] Licenser code migrated into background script.
  • Added wrench button on Add-ons Manager to access settings.
  • Other ongoing work of Rewriting code to use APIs instead of Thunderbird's internal functions see [issue 147] for up to date detail.
  • Moved accounts + permissions code into my own experimental library as users were not prompted to auto-updated due to added permissions.
     

• Version 5.5.2 - 28/04/2021

  Maintenance Items - 5.5.2

  • [issue 148] quickMove: parent folder containing an underscore not suggested as parent if typed from fully this is a regression caused by changes in [issue 135] which allows for entering parent names by entering text within the string if that starts with an underscore or space - e.g. to find all child folders of "001_Test" you could just type "tes/". The regression caused it not to be suggested when typing "001_tes/" as it only would evaluate the substrings "001" and "Test" as possible parents.
  • In some locales the character » is replaced with encoded unicode entry \u00BB in Create subfolder menu item
  • In Thunderbird 89, the options button was not displayed in Add-ons Manager.

  Maintenance Items - 5.5.1

  • Hotfix: [issue 144] Fixed: Mark folders + subfolders read stops at first generation (direct child folder) mails and potentially may have affected parent folders, too.
  • Fixed: The tool menu item "Change the order of tabs" did not update the toolbar after clicking Ok. To make changes visible one had to click "Refrehs Visible tabs"
  • Rewrote the legacy style localization to use the modern method which is a prerequisite for converting the Add-on to a "mail extension" in the future.
  • Version 5.5.1: Completed Hungarian, Simplified Chinese and Catalan locales.

  Improvements (5.5)

  • [issue 135] quickMove » quickJump: When using "/" for parent folders searching for substrings should work better... The Search algorithm now recognizes Underscore _ and Space within folder names so that parent folders with prefixes such as "01_test" can still be found without knowing the number (type "test\subfoldername" to get a match in this example).
  • [issue 134] Feature Request: Escape key to "Cancel quickMove" completely. Before this change, Cancel would hide the search box but keep the list of mails queued to be moved so that more items could be added later. If necessary, the old behavior can be restored in the Advanced search settings dialog.
  • [issue 132] In a single message tab, quickMove used to redisplay the mail after moving it with quickMove. This behavior has now been changed on request to go to the next email. If necessary, this new behavior can be changed via the advanced search settings button in the Single Message Tab box on the QF Pro settings tab.
    
  • Increased maximum subfolders in a dropdown menu from 100 to 250.

  Bug Fixes (5.5)

  • [issue 136] Fixed: There were no folder suggestions during quickJump » quickMove while viewing mails in a virtual folder view (such as search results » or after open message in conversation). This was a side effect of changes from [issue 57].
  • [issue 140] Fixed: Restriction to current server unexpectedly suggests creating new subfolder on excluded accounts. This only happens if there are no other matches found for the folder search pattern.
  • Changed folder tree shortcut from F7 to F9 (consistent with Thunderbird 68). Push F9 to make the folder tree visible or quickly hide it.
     

• Version 5.4.2 - 29/03/2021

  Improvements

  • Added quickMove advanced settings panel for the following new features:
    

    [issue 118], [issue 57] Restrict quickMove results to current server. With this option activated when searching only results from the currently selected account are included in the search.
    I also added a list of accounts to explicitely exclude selected servers from search results.

    [issue 74] User Interface to enable silent mode - this disables notification after moving mails.

    [issue 119] The maximum number of search results can be changed from 25.

    
  • [issue 103] quickMove now also supports copying folders. To copy a folder, hold down the CTRL key while you drop it on the quickMove button. Queued folders are now also properly listed in the quickMove menu:
    
    You can use this panel for a number of functions, such as not showing the unread status or excluding a folder (and optionally also its subfolders) from the quickMove search results. You can also prefill a different from address and to address when writing new mails. To display, right-click any tab and select"Tab-secific Properties" from the QuickFolders commands submenu.
  • Improved layout of numeric inputs in Settings dialog.
  • [issue 117] Added color picker for text color in tab-specific properties.

  Bug Fixes

  • [issue 115] Fix restoring of config values. Some general » layout settings were not restored properly even when they were saved during backup.
  • [issue 116] Custom Text color in tab-specific is not set on tab.
    
  • Regression in 4.5 (fixed in 5.4.1) [issue 123] Fixed: An error in the French translation leads to the Settings screen not loading.

  Thunderbird 78 Regressions, Tb 88 and beyond

  • [issue 115] Fixed: Restore does not load some general » layout setting.

  • [issue 114] Make QuickFolders compatible with Thunderbird beta 88.0b1

    • Fixed: Support Pages did not open anymore as content Tabs have a different parameter set.
    • Fixed: layout of advanced tab properties broken due to deprecated grid element.
    • Fixed: Copy » Move folders uses new MailServices.copy object
    • 5.4.2: bumped max version to 88.0b2 so current beta users can keep testing QuickFolders.

    Removed legacy iterators for folders

    If you find more regressions associated with Thunderbird 86 or higher, please report them at issue 114 linked above.
 

• Version 5.3 - 23/02/2021

  Thunderbird 78 Regressions

  • [issue 106] Thunderbird 78 regression: backup did not save general » advanced » layout settings.

  • [issue 108] Thunderbird 78 regression: Some changes in options window were ignored and not stored.
    Settings that could not be changed from the options screen:
    Premium » quick move display format
    General » Message Navigation » Go to next unread mail

    Also, many layout settings were not updating immediately through the User Interface, because of broken instant apply settings.
  • [issue 111] Paint Mode stopped working in Thunderbird 78. You can now use Paint Mode again from the QuickFolders tools menu to change the colors of multiple tabs. (For best results use the flat style theme).
    

    Activate paint mode,

    then select a color from the palette and click on the tabs you want to change:

    The colors displayed depend on the selected "Palette for Colored Tabs" which is a global setting and offers 3 choices (Standard, Pastel and Night Vision for dark themes).

  • [issue 88] Fixed highlighting of drop targets when dragging mails into a subfolder.
    

  Improvements

  • [issue 82] Improved sorting of search results during quickMove » quickJump. The results are now sorted mainly based on alphabetical order (with boosts for folder names that start with the searched text and completely matching the search text). As before, partial strings are only matched from a length of at least 3 letters.
  • [issue 109] Mark Messages read in Folder and the subfolders recursively did not display as expected.
    This additional menu item that can be used to set all mail in subfolders to read was only displayed if the actual folder of the tab itself had no unread emails, and only child folders had them. Configure this command in QuickFolders settings » Advanced » Menu Configuration » Mail Commands:
    
  • [issue 37] When no match is found using the "/" in quickMove box, display "No matching parent folders!" instead of "..."

  Other Bug Fixes

  • [issue 101] If multiple categories are selected, closing QuickFolders settings reverts to "Show All".
  • [issue 107] Restoring general » layout Settings only works if option for restoring folders also active.
  • [issue 110] "Tab-specific Properties" overwrites To Address when clicking Write from Address Book.
  • [issue 112] Reading List menu - Add current Item not working

  • [issue 114] Make QuickFolders compatible with Thunderbird beta 86.0b3
    Removed grids from options screen to suport Thunderbird 86 and higher.
    Using renamed function FtvItem for creating Recent folders list.

    If you find more regressions associated with Thunderbird 86 or higher, please report them at issue 114 linked above.
 

• Version 5.2 - 22/01/2021

  Improvements

  • [issue 75] - Support moving folders with the quickMove function. You can now move one or multiple folders by dragging them from the tree to the quickMove button or hitting Shift+M (with a Pro License) while the folder tree is highlighted.
    Up until now, you could only move folders by holding Shift and dragging to a QuickFolders tab, which was a significant limitation.
    
  • [issue 92] - do not overwrite 'To address' from advanced tab properties when replying to an email!
    With QuickFolders Pro a to address can be auto-populate in the advanced per-folder settings. This should not happen when replying to an email; from no on it will only populate when writing a new or forwarding mails:
    

  Bug Fixes

  • [issue 94] - Tb78: Tab-specific properties displayed in incorrect screen position.
  • [issue 23] Fixed: quickMove aborts with "Nothing to do: Message is already in folder" if the first mail in the selection is already in target folder. This may happen if you drag mails from a multi-folder view such as a search results window. It can also happen if you execute the quickMove command after a while and you (or a filter) have moved some of the mails to the target folder already.
  • [issue 96] Drag and drop issue in Thunderbird 85 beta. Although I fixed this particular issue I make no guarantees for any functionality if you are using beta versions. I can only support the current ESR version Thunderbird 78.1 - 78.* fully,
 

• Version 5.1 - 11/12/2020

  Thunderbird 78 Conversion

  • In order to maintain full functionality for the next 12 months forward, QuickFolders had to be rewritten as a mail extension with experimental API, which will require full permissions on installation. As regards being allowed to do stuff, it is actually not different with any classic Add-on: they always had full access to all functions within Thunderbird. The modern mail extensions will have much more tightly managed permissions - eventually QuickFolders will also use this more modern approach - but the APIs for this have to be created and accepted by Mozilla first. This means a lot of ongoing work for the nexty 12 months forward - please support this with a license or donation:
  • You can buy a license here. This is the preferred way of funding all the ongoing work and improvements.
  • If you are not ready for a license you can also donate from here

  Bug Fixes

  • [issue 72] Fixed: Category "_Uncategorized" erratically showed all categories after moving a folder to another category
  • [issue 76] Fixed: Recent Folders List is not updated until Thunderbird is closed and reopened
  • [issue 80] Fixed: Recent Folders list not updated when moving email using drag and drop to the folder tree. I have made the updating of this folder time stamp somewhat more aggressive, but avoiding to add folders like Inbox, Sent, Archives, Drafts, Junk, Trash and Templates because they would always end up on top.
  • [issue 79] Fixed: Drag over color + Dropmarkers when reordering Tabs not working
    
    This was caused by an experimental style selector [-moz-drag-over] which has been now removed by Mozilla due to little take-up of the HTML community. I had to rewrite these parts using pure JavaScript.
  • [issue 81] Fixed: Current Folder Toolbar display - text is always black
  • [issue 84] Fixed: Can't drag envelope icon in Navigation bar (a.k.a. Current Folder) to a folder » QuickFolder drop target. Also the Navigation Bar is hidden if multiple mails or a thread is selected.
    
    Drag envelope icon to move the currently selected mails to these targets, or into the folder tree if needed.
  • In the dialog "change order of tabs" the Up and Down labels on the buttons were not rendered for some yet unknown reason - this is now worked around by removing the button styling from these elements

  Improvements

  • Hide option to extend license if it is already more than 1 year into the future.
  • Hide popup screen for licensed users who have > 40 days left on their license
  • Improve legibility of dropdown items in themed QuickFolders options dialog. Especially affects users of dark themes.

  Miscellaneus

  • Removed Encryption test code from options.js
  • validateFilterTargets moved to other module to avoid console errors.
  • Improved reopening any support sites already open in a tab by jumping to the correct place if necessary.
   

• Version 5.0 - 17/11/2020

  This is the new version of QuickFolders whis is fully compatible with Thunderbird 78.

  Changes » Work Items

  • Removed backwards compatible (shim) code and all code implementing cross-compatibiliy for SeaMonkey and Postbox. The code base had to be forked into a new branch, so if I backport bug fixes this will double my work for the legacy Thunderbird users.
  • [issue 35] "Skip Unread Folder" hides "Add star" function... the Shortcut for skipping unread folders works even without pressing the Shift key

  • New icon layout base on the new Photon Design System for Thunderbird. The fantastic new Icon conversion was kindly and expertly done by Richard Paenglab.
    

    The Navigation Bar (current folder toolbar) has also been redesigned:
    

    Apart from that, all menu configuration as well as theming options and colors for the QuickFolders Tabs are still available:
    

    Folder tree icons can also still be overwritten with external icons (here is a small icon collection for QuickFolders Pro users)
    

  • Removed nsIRDFService dependencies
  • rewrote preference bindings in all dialogs
  • Added new Thunderbird 78 compatible Icons (svg)
  • rewrote search algorithm for missing mails in reading list - clicking on a missing mail there brings up a search dialog. Unfortunately this was not populated with meaningful search conditions
  • Klaus Buecher (@Opto) did the initial conversion of all XUL interface and fixed some bugs. John Bieling (from the Thunderbird team) helped with the WindowLoader implementation and fixing the broken preferences. Many thanks to both of themn for their fantastic work!

  Known issues

  • Any dragover styling (special color, dropmarkers when moving tabs around) is currently broken - this is caused by an experimental style selector which has been now removed by Mozilla due to little take-up of the HTML community. We will need to recode these parts using JavaScript.

Older versions (for versions of Thunderbird before 91.0) are listed here
