I had this problem for a couple of days. I called support (if you can call it that) and they walked me through the usual garbage of deleting histories and resetting the browser to "original" settings. Mind you, I tried 3 browsers, Edge, IE and Google Chrome ... all failed and since they had me delete all history, etc., all the usernames for various web sites that I saved are gone. I told the "support" person that these activities were useless since the day before I called I could access my account and had made no changes ... waste of breath. I was told that the "next" level of support would call me within 24 hours ... NEVER HAPPENED. However, AUTOMAGICALLY, I can now access my account and email. I'm thinking they just didn't want to calll me to tell me about their embarassing "fix". Good luck with comcast "support".
