I encounter a strange SSL error messages in Mac laptop with https connections.
It only happens on some websites such as facebook, twitter with Firefox and Chrome and only happens at work. It is likely IT is doing sniffing the https traffic with firewall, since the same websites/browser/system works just fine at home internet connection.
Even stranger, with Safari those sites work just fine at work.
Is there anyway to get details on which certificates, CA were used by various browsers that authenticates the websites.
