Last week my usually reliable 'Thunderbird 115.8.01 on iMac 10.13.6 has suddenly gone haywire.
* In the folder pane, multiple folder duplicates reappearing even after deleting them. (See images)
* And when I delete messages, they appear in the trash folder, only to disappear and repeatedly reappear - back into the message INBOX.
* Also, after making a change in the Notification section to turn off the notice sound, and although the sound turned off, so did the auto-disappear function. Now I have to manually "close" each and ALL notification notices one-by-one. The new problem is: now the notification option section has disappeared in settings.
(No image for this one. Nothing there!)
Bug? Or something else?
Please help.
P.S. I ran both of my antivirus programs twice. Each over different days and both declared' my system clear and clean.
