Good morning
Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.
Everything in the program freezes up. I cannot even close it.
I am running Version 140.8.0esr on a Windows 10 PC.
Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.
I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.
I checked for crash logs but there are none.
I have run out of ideas as to what to try next. Does anyone have any advice?
