I'm having the problem that is reported here and traced to QuickFolders (as against to this fixed-20-years-ago Thunderbird bug). I verified that QuickFolders was the (at least proximate) cause by disabling the AddOn and restarting Thunderbird. I have the problem on Linux. I don't think I see the problem on Windows.
Hello there.
