Just fine here with Firefox 16.01 Bewertet mit 5 von 5 Sternen

After having installed protocol 'Microsoft TCP/IP Version 6' from within XP-SP3, even though I remain at this time IPv4 restricted, SixOrNot allows me to discover when a website is "IPv6 ready". Not to mention "information about all the domains contacted in order to load the page" (which is my first motivation). Nice.
