Thunderbird 91.3.1 update not connecting to server
Since Thunderbird updated to 91.3.1 all my 4 email addresses time out when trying to connect to their servers. I can't receive or send any emails. Thoughts?

Sounds like a proxy problem or AV software.
Try starting WIndows 10 in safe mode

Still in Windows safe mode, start Thunderbird in Troubleshoot mode - https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

In troubleshootiung information it says "The Update could not be installed (patch apply failed)". How can I reinstall or revert to previous version please?

That did it. Thanks so much.
Do you know (or have a guess of) the precise cause?
No idea, I'm afraid. I don't use a proxy. I use Norton Security but nothing was reported there.
