Changed my gmail password >>> thunderbird fail.

Thunderbird Passwords and sign in

After changing my personal gmail password Thunderbird wanted to verify but got "400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

The process worked on another PC on version 140.2.1esr but not on my desktop using version 140.3.....

How can I revert my desktop to version 140.2.1esr?

You cannot change your account password via Thunderbird. To do this, you'll have to login to your Google account via browser, and change the account password there.

Once done, delete the OAuth token for your Gmail account in Thunderbird. At the top right of the Thunderbird window, click the menu button ≡ > Settings > Privacy & Security > Passwords > Saved Passwords

Thunderbird will prompt you to re-authenticate the next time it's needed. For the OAuth authentication to succeed make sure cookies are allowed in Thunderbird, and no other application on your computer blocks TCP port 80, e.g. like a local web server, or anti-virus software. Also make sure no VPN is active at the time of the authentication attempt.

The problem was that cookies were turned off.
