Updating an old install of Firefox (another computer that I'm rebuilding from scratch because of a crash). My computer doesn't like the security certificate which is issued to edgecast, not Mozilla. If I go to the same page using this computer (my laptop, Firefox ver. 18.0.1) I get a certificate issued to Mozilla. Is this difference legit or a security hack? PS. My email isn't up yet, so emails to me might not get through. I'll stay here for a while to see if anyone can help.
