Unable to add a Gmail account - Unable to login at server. Probably wrong configuration, username, or password
When I attempt to add a Gmail account, I get this error - "Unable to login at server. Probably wrong configuration, username, or password"
Below are the steps with screenshots: - checked for no cookies to prevent Google from asking for an actual login - no stored google passwords - didn't put in my password on setup - TB finds the available configuration - prompted to login at google - add google password - allow access - error message
I have restarted Thunderbird. I have checked for updates (even though I have it on auto-update).
Are there settings on my Google or Gmail account that could prevent this from working?

I assume that is under Settings > Privacy & Security > Web Content (see screenshot). Or are you referring to a setting someplace else, like my default browser?
Verified it was checked. Shut down/restarted Thunderbird. Same result.
Tried out Troubleshooting mode (as suggested in https://support.mozilla.org/en-US/questions/1478092), same result.
I do run a firewall and Adguard but verified nothing is being blocked.
The frustrating part is that gmail worked earlier this year and recently (not sure on the timeframe, but in the last 4-6 months) started giving me errors, saying it couldn't connect. I read through a bunch of forums and troubleshooting docs here at the time and decided to back up the mail file, delete the account, and re-add it. I couldn't get it to add (same error I've written about here) but I left it alone until I had a chance to spend some time trying to figure out what is going on.
Since I hadn't made any changes to Thunderbird when this all started, I assumed either an update to Thunderbird changed something or Google changed something. I'm not sure which yet.
Well, I can't see whatever might be the problem. Maybe someone else on this forum will have suggestions.
