Rated 5 out of 5 stars

First it was not working with Thunderbird 143, but with the suggestion below (quickfolder 6.13) my problem is solved! Thanks

6.13 is in review - you can already get it from the QuickFolders Github on the releases page. Can't post the link here because it will delay the reply - but you can contact me directly if you can't find it.

this is very practical!!!
Since today I have a Thunderbird 6.0.1, so I have to wait till this addon is updated.
Because it does not yet work on this Thunderbird version. I hope it will soon be released!!!!

in the meantime you can download the current pre-release (2.7.3pre4.xpi) here: http://downloads.mozdev.org/quickfolders/
