I've been having a strange problem for about a week now - not being able to connect to the FF website. I'm getting an "Access is prohibited by the site administrator [767]" error message. I can only access the site through a VPN or from a cellular network.
I've contacted both FF support and my ISP, and neither one is apparently blocking any traffic that could be causing this. I've tried doing some traceroute diagnostics and there appears to be some connection points that are responding with timeouts. Has anyone had similar problems? Any ideas how this could be fixed? Also can someone confirm that the 767 error message is not from the FF servers?
