Hi,

I've been using Thunderbird for years and have upgraded many times. I've never had any major issues until just now. I upgraded from a recent 91 version to the latest 102 version as of today (11/15/2022). I upgraded on a Windows 8.1 computer. Did the upgrade because I'm setting up a new Windows 11 computer and I want to migrate my Thunderbird email over to the new computer. Thought it would be best to use the newest version on the new computer, so wanted to migrate from the newest version from my old computer. After upgrading I opened Thunderbird and it got stuck dealing with two gmail accounts I have configured in it. Cursor was circling and on one account my Inbox showed empty. I have two other accounts with other email providers and they both seemed to be OK. I closed Thunderbird and reopened it and the same thing happened. I logged into my gmail account on the google web site and my Inbox was empty. It was not empty prior to the upgrade. I deleted the gmail accounts from Thunderbird for now. Tried to reconfigure one of them and it told me it already exists. Don't think I have any way to recover my Inbox emails at this point. Not happy! I plan to downgrade back to 91. I made a copy of my profile file before the upgrade, so I will use the backup copy when I downgrade and hope I don't lose anymore email. Don't see any way to report bugs, so I'm posting this here. Lisa
