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

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.
