As well known, Google announce its service for IPv6 users named as "Google over IPv6", which make a great convenience for Ipv6 User like me. But during my usage of firefox over IPv6 network, I found sometime firefox will go to IPv4 address when I visit a dual-stack website, it is so bad for me because my IPv6 link is preferred and even free. I am looking for some solution in "about:config" , but I just find only network.dns.ipv4OnlyDomains exists, but no network.dns.ipv6OnlyDomains. I think it is necessary, and will be more urgent after ISP like Tomcast to promote its IPv6 ISP service

Reproducible: Always

Actual Results:  
sometime firefox will go to IPv4 address when I visit a dual-stack website

I think no, the two bugs which you mentions are about the auto selection. But which I wanted is a manual option to make user can select IPv6/IPv4. It will be complement of auto selection.

And I think it will be not so complicated, because similar option exists for IPv4

Due to some filtering in some areas, this functionality is really necessary to reach some websites without explicitly entering the ipv6.* prefix in the address bar.
