Rated 5 out of 5 stars
This is a fantastic add-on, but now the folders are lost whenever I restart Thunderbird. I'm using TB 3.1.15 with QuickFolders 2.9This review is for a previous version of the add-on (2.9).
... please go here:
And yes, this bug is already fixed - Simply install QuickFolders 2.9.1 <:o)
The bug only affects TB 3.0 and older - remember, the current release version of Thunderbird is 7.0.1
