Gmail oauth gives Authentication failure after restarting Thunderbird

I am continually getting the Authorisation Failure message when trying to open Thunderbird.

Please post a screenshot of the error. https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem

This is the message I get for all three accounts:

> All is fine until I close down Thunderbird and then open it again.

So after installing Thunderbird, you are successful in completing the oauth authentication process for all three accounts, but then after restarting Thunderbird you are prompted again?

And if you go to Settings > Privacy > Passwords > Saved Passwords you see the oauth tokens for the accounts, similar to this screen shot?

Do you have cookies and javascript disabled?

Hello Wayne - I have just checked and the two that I have reconnected and the passwords saved.

Cookies are enabled. Not sure about Javascript? How would I check that?

Thanks

If you are still having trouble, please try https://www.thunderbird.net/en-US/download/daily version 156 - it will install in a separate directory - and let us know how it behaves.

This has been an issue for me for a few days now. Should I even class it as a tech support request or does it deserve to be classed as a bug? I think the latter because it doesn't prevent me from accessing my email accounts. It's just a message at Thunderbird startup. Every time.
