Legacy Versions

This page lists older versions of QuickFolders. QuickFolders 5.15.2 is fully compatible with the latest version of Thunderbird (102.10) - and currently supports up to version 110 beta 4. I am currently working on fundamental changes for Thunderbird 115 which will be released in summer 2023 and has a completely new user interface "Supernova". This requires 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.


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)].
