I was completely satisfied with Thunderbird until the big update in autumn 2023. I've used it for over 15 years, with many mailboxes, with virtually no bugs. Since then I have encountered the following errors. The last one is the most painful: - Gmail accounts sometimes need to be re-authenticated

oauth tokens can expire. Is the frequence the same for each account? How frequent?

- When I switch to a folder, I often can't see the mail there and have to switch to it again

Does this happen with Thunderbird started in Troubleshoot mode? (Help menu)

- The "Get Messages" icon is too small, inconvenient to use

Alternatively use F5 for current account, or shift+F5 for all accounts.

- The display of the number of unread messages is not as transparent as the old bracketed solution

This can be worked around with CSS

- Something has changed with the new message indicator (blue color) algorythm, because I sometimes miss a new message since then, what never occured before the update

Pop account or imap?

- If I don't use it for a while TB freezes several times a day and have to restart it

Does this happen with Windows 10 started in safe mode?

Hello,

thank you for your answer.

"Gmail accounts sometimes need to be re-authenticated" - I manage 11 email accounts through TB, of which 7 is a Gmail account. If I remember correctly I have to re-authenticate only the accounts I don't use daily or even weekly. It's not a big pain, however.

"Does this happen with Thunderbird started in Troubleshoot mode? (Help menu)" - It's happening seldom, I don't want to spend much time on this.

"Alternatively use F5 for current account, or shift+F5 for all accounts." - Thanks, I will, but it's not the same...

"This can be worked around with CSS" - Thanks, I will look up how to do it.

"Pop account or imap? " Pop. It's something like if I click on a folder then not only the blue letters found in this folder turn black but all of this account, even if in different folders (I have a plenty of them).

"Does this happen with Windows 10 started in safe mode?" - I haven't try, I use my computer too intensively to waste time on restarting in safe mode if it's not absolutely necessary. By the way, after a half year I didn't experience it in the last 2 days or so.

Thank you again.
