The last couple days I have messed up my email accounts on Thunderbird. It started with sorting out a problem with Xfinity. I am getting a pop up on Tbird to enter my password for mail.comcast.net, I have two mail.comcast.net logins showing in Tbirds passwords that are both "mail. comcast" and not "imap". I got a pop up also saying enter my imap password but my Tbird doesn't look like l ever had an imap password. So what do I need to do? Can you suggest a more user friendly Ap? Tbird has been working pretty good until now. Thanks.
