Generally I have found this add on really useful. However, as of Thunderbird 68.0, it is broken. TB disables it. You can enable it, and it partly works, but the folder pull down at the top of the window does not work (either because that is part of this addon or this addon interferes with it.) Fortunately for that there is a workaround - soo posting by user c42623 from 2020/01/06

I know we aren't supposed to post bugs here, but the support link generates "Internal Server Error" response. Today right-click stopped working correctly. It works the first time or two, but after that right-click stops responding. If I use Shift+M to select a folder in "recents" to move a message to, then right-click starts working again.

This review is for a previous version of the add-on (1.6).

I second the report about the (right click) context menu no longer working properly (TB 52.5.2) (and thank Metallian for his workaround). I also commented on another report of the right click/context menu issue on Thunderbird Bugzilla.
