Rated 5 out of 5 stars

Every time I open thunderbird now I get the following message: "QuickFolders was successfully upgraded to version:2.8"
and it open a mozdev.org web page. Any way to stop it from doing this?

This review is for a previous version of the add-on (2.8). 

Yes we can!

You found [bug 24389] which affects only a few users.

Please go to http://downloads.mozdev.org/quickfolders/ and then download the patched version QuickFolders-tb-pb-sm-2.8.3pre16.xpi - this will fix the issue! You can also mail me directly for support
