When reading GMail I get "Sign in to continue to Mozilla Thunderbird Email". When I put in my GMail address and click "Next", I get another message that says, "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." I can't find anything in my Google account that is requiring this additional sign in to check email. Anyone know a fix for this?

Cookies and Javascript in Thunderbird must be enabled for the OAuth 2.0 setup process to work. See https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20
