gmail/google credentials error
I have changed my passwords on 2 gmail accounts I import to TB. Usually when you do that and TB retrieves email from gmail, you get a credential popup because the password doesn't match. Usually when you get that popup you click "next" and put the new password in and everything works as it should. I have been messing with this for 2 days now. I get the gmail credential popup, but when I click "next" to continue, I then get an error 400 from google? You can't do anything else after that. That darn popup just keeps coming and coming every time TB tries to retrieve email. Anyone else having this issue and found how to fix it? Is it a TB issue or gmail/google issue?

Make sure to allow cookies in *Thunderbird*. https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20
Also make sure nothing else on your computer is using TCP port 80, e.g. like a local web server. Also some sort of anti-virus software may block that port.
Do not use a VPN when authenticating with Gmail.

christ1: Outgoing is set correctly. I don't see an incoming server option. This account has been fine until I changed the password while signed into gmail. Then went back to TB and the issue started. Changed the password in TB and it was still goofy. In cookies, I made an exception for google. It's working now but I don't see why simply changing a password would cause me to do the cookie thing for ALL my accounts? All the other accounts are/were fine.
Don't make an exception, just allow them. Turn them off again after if you like. But almost all of the issues with Gmail authentication occur because cookies are a mess, either because the correct exception are not made or because other software keeps over riding that things like antivirus product and ccleaner are all suspect as they do little to improve security but manage to mess up a lot of folks that use anything but a web browser.
Wayne Mery: The above help with cookies seems to have solved it, but I sure would like to know why this happens when a password is changed. I have quite a few gmail accounts and the only 2 that went goofy were the ones I changed passwords for. If my settings are the same down the line for each, I don't see why only a few would change on their own.
Changing the account password will invalidate the OAuth authentication token for the account. Thunderbird will prompt you to authenticate again, which will only work with cookies enabled.
