After Reinstalling THUNDERBIRD. and importing my old profile/settings (mail
box; Imap; extension...)

My Quick Filter extension does not work any more.

I tried to uninstall and re-install "Quick Filter" but it didn't change
anything: I always had this kind of message when I tried to create a filter:
"Create filter fails with error "idMail is null"
 I thought I found a patch on the Bug 25758's page here on "Bugzilla@Mozdev"
and tried to install it.

But after the restart of THUNDERBIRD; when I try to create a filter here is
what I can read :"Erreur d'analyse XML : entité non définie
Emplacement : chrome://quickfilters/content/filterTemplate.xul
Numéro de ligne 126, Colonne 6 :                                      
<listitem label='&qf.filters.template.domain;' value='domain' tooltip=""/>
----------------------------------------^"

I add a screen copy of the window containing this text.

English is not my native language and I'm a user not a "dev" ;o)
So I don't what I should add.

Except: Thanks if you can help me.

WIL.

Window with error message

The error is probably caused by a missing translation in the French locale,  I
can fix this for you once I am back from my holidays ( next week ). Also our b
mozdev server is still in maintenance mode v shop it is possible that I have
made more improvements in the meantime.

qF 2.6 prerelease 60

Try this version I added replacement strings fore all missing strings in other
locales (including French)
