How can I get Firefox/Chrome to reach IPv6 websites?
Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache\Parameters
Add a DWORD value:
AddrConfigControl = 0
You will have DNS resolving through the Teredo tunnel.
In Firefox go to about:config and look for
network.dns.disableIPv6
Make sure that is set to false which it should be by default.
Then test it by going to http://test-ipv6.com/
If the test at test-ipv6.com passes, and you still aren't getting the dancing kame turtle, also disable network.http.fast-fallback-to-IPv4. Once I did that, the turtle showed up for kame.net
