Can't seem to get thunderbird to connect to my xfinity (comcast.net) email... tried full reinstalls, changing the password, and all the steps in this: https://support.mozilla.org/en-US/questions/1437228 As well as trying "normal password" instead of OAuth2. The OAuth2 option does not seem to generate a pop-up to authorize that way. Using other 3rd party and logging in via browser also work. Does thunderbird need to update something to fix the issue? Its been only a few weeks now for me that this was an issue.
