Make sure to allow cookies in Thunderbird.

Thank you christ1, but all cookies are allowed.

I'm starting to get pretty unhappy about this, I've tried a lot of things: - check settings less-secure apps on my google account - run TB in troubleshooting mode - turn off antivirus - clear cache and cookies in TB - reinstall TB on lower version (91.7) I don't know what else to try.

It looks like TB password wizard don't save the password and the account isn't authenticated. TB then still requires a new login, which does not work properly.

Can you please advise something?

Btw. I see these errors in debug console - see the attached picture.

Can it help?

THanks for the console log. Definitely oauth related. See https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20 which is mentioned in release notes https://www.thunderbird.net/en-US/thunderbird/91.8.0/releasenotes/

What do you see for the account in Settings > Privacy > Saved Passwords ? And cookies are enabled?

I don't know whether this is related - there was a recent similar problem where the error said JavaScript was disabled - do you see anything about JavaScript when the Gmail prompt fails? Also just to be quite sure - cookies are on in Thunderbird settings - not just settings for cookies in your browsers. See this article https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20 and https://support.mozilla.org/en-US/kb/privacy-panel-settings-in-thunderbird

thank you, I saw that page I cleared all passwords, so there is no pass now All cookies are enabled.

@AgnesRM and I don't see any warning or error about JavaScript when I allow access to a google account cookies - I am quite sure that I am in TB settings

I am having the same problem, and this is what I found. I noticed that TB ver 91.7.0 was working on my laptop with a clone of the profile on my desktop computer. So I removed 91.8.0 and installed 91.7.0 on my desktop. Then I copied the profile from my laptop to my desktop. Problem is fixed. I conclude that TB ver 91.8.0 breaks my profile in some unknown way. Downgrading TB and restoring the profile works for me. Good luck!

ok, my problem half solved - change the Authentication method from OAuth to Normal Password and everything is working The question is what it will look like after May 30 when Google changes the authentication method.

Anyway, thank you very much for all your efforts.

thank you @Rich Kellog! I'll try your progress when I have some time.

Jan, can you file a bug report for your issue, and include the console screen shot? https://bugzilla.mozilla.org/enter_bug.cgi?product=Thunderbird

@jan: I believe your post is the best answer. Apparently, the "unknown way" that TB ver 91.8.0 broke my profile was by changing authentication to OAuth. I haven't test this, but I am confident that is what happened. [Rich]
