after update to Thunderbird 78.2.2, unable to open emails

more options

Computer is at work, where several computers are connected to one server.

Computer I used updated to Thunderbird 78.2.2 on Monday (2020/09/14). After that update, I am unable to ready any emails. I have a green progress bar on the bottom right of screen that is full. I have a message that the computer is 'connected'. Selecting an email does not display it in the Message panel, and double-clicking email to open in another tab gives an empty tab.

I am able to access emails through Thunderbird on other computers, so that must mean a problem with the setting on my computer and not the server... right?

Can you try starting thunderbird on safe-mode (no add-ons)? If you have thunderbird on other computers connected to the same account you might compare and set the same also on this computer what is on an working one.

Did try opening in Safe Mode, disabling add-ons. No change.

Also have compared the basic settings with other computers in office and can't find any different settings, but I also have no idea what I should be looking for.

You might try to downgrade as a last temporary solution. Check question 1304483 where I've mentioned the steps (I'm not allowed to post links)

There are some reports in the last 2 days that TB upgrade has caused some profile file to be corrupted - I assume this might be the same also here. Far as I've tested on a fresh installation of TB in a virtual machine there were no issues - so, probably, something happen during the update in some cases.

I had the same problem rendering v.78 unusable. Luckily I have 4 Macs and could downgrad to v. 68. See my post "How can I return from Tbird 78 to 68?" for how to downgrade if you have a working copy of v.68 on another computer. I have done so successfully.

FfTh202009, I cannot find the link on the Thunderbird download page for 68.0.9, but there is a 68.9.0, is that the one you mean?

Eric, the other computers I have access to have upgraded to 78 already.

The current version prior to the v 78 disaster is 68.12. Be sure to turn off the automatic update when you do install it (in Preferences under Advanced, then Updates). I don't know if someone at Thunderbird can send you a link to download 68.12, but 68.9 probably will work just fine.

Downgrading to 68 is a valid stopgap measure, but not a viable long-term option. To avoid most of the issues with running 78 on a profile that was used with 68, create a new profile with 78, add your accounts, then transfer local mail, address books etc. manually from the old profile to the new one. Help/Troubleshooting, about:profiles, to create and manage profiles. Install add-ons that are working in 78 (current list).
