       I have no clue what you are talking about being coded in
       /etc/hosts...

       you can check DNS if it returns ipV6 addresses for hosts or if
       there are
       snags/delays in trying to resolve names from command line

   p3490.htt is in my /etc/hosts file as something like:

   2701:24:2:1:0:1:2:3   p3490.htt

   I can 'ping6 -n p3490.htt'

   But putting a url of http//p3490.htt does not work....

DNS can be real slow when IPv6 is enabled.  For instance the following firefox delta would speed up firefox on IPv4 connections.  Maybe you need to turn it on?

You may have already found this, but it helped when I had the same problem.

In firefox type in about:config,
filter for 'ipv6' you should have an entry for network.dns.disableIPv6
right click on it and 'toggle' it to a true value,
restart firefox and see if it helps.

Um, as the original poster, I WANT IPv6.  Not make IPv4 lookups faster by ignoring AAAA records.

Further testing has IPv6 working just fine.  Thing is when I enable the HIP API intercepts, FIrefox does not work.  Like they are doing something 'non-standard' with the regualr TCP socket API so that HIP can't slide in there.  I tried disabling a number of options, thinking it might be some security setting, but if it is, I have not found it.
