I have just I upgraded to TB ver 78.4.0 (32-bit) the upgrade seemed to go normally but the new version did not work. in detail: 1- i have received no new email on either of two google-based email accounts since the udgrade. 2. I continue to get email on the Google Email page for at least one of the accounts on the same computer. 3. when i click on "Get Messages" nothing happens 3. Past messages are still in my inbox and they open when selected 4. messages will not actually send but I con click on write or resend a previous message and type and send and go through all the steps BUT they are not delivered and the only error message I get is that the message wasn't saved. 5. I have started TB in safe mode - no difference 6. I have shut off ESET NOD 32 - and No change

Try to start Windows in safe mode with networking enabled.

Still in Windows safe mode, start Thunderbird in safe mode. Does the problem go away?

The problem goes away when I start windows in safe mode. TB in normal mode. What is the likely problem?

What is the likely problem?

Antivirus: ESET NOD32 ver 14.0.22.0

Windows safe mode disables anti-virus software, which is most likely the culprit. These are some generic suggestions to avoid problems with anti-virus software.

Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. http://kb.mozillazine.org/Profile_folder_-_Thunderbird

Don't let your anti-virus software scan incoming and outgoing messages.

Don't let your anti-virus software scan attachments.

Don't let your anti-virus software intercept your secure connection to the server.

Remove any add-ons your anti-virus software may have installed in Thunderbird.

Keep it working. http://kb.mozillazine.org/Keep_it_working_-_Thunderbird

And last but not least, backup your Thunderbird profile on a regular basis. https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile

ESET suggests a very simple solution, and it worked for me. Read this discussion: https://support.mozilla.org/sv/questions/1316142#answer-1375059
