For the last 3 days every time I try to access my email account, "xfinityconnect.email.comcast.net", a warning comes up saying Firefox won't let me connect. "Warning: Potential Security Risk Ahead". I have scanned my computer and removed any threats, viruses, malware etc. but the warning continues to block my mail program. Help!
