Norton 360 updated last night and now Thunderbird isn't working. I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help. It also kept saying its own homepage was a security risk and blocking it. I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it. But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow? Any idea on how I can fix this?
