Does not work in what way specifically? Why restart?

I just came back to my computer and I clicked on an email. the email did not open and the hour glass started. I tried to close Thunderbird and I got the popup window (not responding) which allowed me to wait or close the program, which I did. I went back to the start program menu and restarted Thunderbird. It then appears to work normally. This problem stared Oct 12 when I restarted Thunderbird and the update (115.3.2) installed. This has happened several times. There is nothing else on the computer that doesn't work. I have used Thunderbird a long time and has worked perfectly.

Thank You

I forgot to say this is Windows 10 that is up to date.

I just was just writing an email response and the program stopped responding. I close it and restarted the program. Thank You

Thunderbird not responding today when I tried to open it this morning. Had to close the program and restart.

• Please start *Windows* in safe mode with networking enabled https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
• Still in Windows safe mode, start Thunderbird in Troubleshoot mode https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

Does problem go away?

10-19-2023 After doing nothing for 2 days it looks normal. Might not be fixed yet.
