Thunderbird Support Forum

Good morning I have updated Thunderbird to the lastest version 115.6.0 (64-bit) on my Mac with Ventura 13.3.1 (22E261) and now I can not see my mailboxes and folders. Have tried everything - nothing works. Rest bookmarks work. Contacts and other functions. I can create and send letters from any of my mailboxes, I can search letters in all mailboxes in search field, but I can not see on the left bookmark nothing - empty list of mailboxes. I have download the program again, reinstalled, changed Thunderbird file in Programms - same thing. Please help.

After updating TB from 112 to 115 the display window is after starting mostly blank. The email folder tree is hidden left. When I pull it to standard location, when I click to the message folder to see the emails, they do not appear on the right. I need then to reset the screen setting to get to the standard classic theme. This holds only short time and again I have a blank screen as attached. When I click to File and then on Exit, it takes very long to close the TB. Closing the TB wit the right cross top works immediatelly. In my case I have a big folders (few GB each) and multiple emal accounts. I really have to say, that in speed and friendly usage is the 115 step backwards from 112.

My open emails from previous Thunderbird sessions have blank tabs and empty message windows. How can I get them visible again? The tabs serve as a sort of To Do List, which is now gone. Please see picture. Thanks.
