If a user using Firefox browses to a website on a server (Windows 2008) that has been updated to use TLS 1.2, what would happen? As I am a newbie to this can someone explain what the process is when a SSL or TLS handshake occurs and what potential problems can arise?

SSL protocol versions generally are not exclusive – the same server may offer TLS 1.2, 1.1, 1.0, SSL 3.0, and even SSL 2.0 for the ancients. Problems only occur if the client and server have no supported versions in common. In other words, a typical upgrade would not affect older clients.
