    I see a comcast.net <http://comcast.net> in your address, which
    probably means this is the
    problem:

    https://bugzilla.redhat.com/show_bug.cgi?id=459756

    It is random, but because you use firefox more, you see it more there.

    I got rid of the problem by running named as a local dns cache and
    starting it with the -4 option so it only does IPv4 requests.


That's weird, I've been seing this a lot too. I use dnsmasq as my local DNS cache, but Firefox keeps asking over and over again for the same addresses (I mean it keeps displaying "Locating xxx" when xxx has just been accessed, which means it's on dnsmasq's cache).

I already have "network.dns.disableIPv6" set to true on FF's configuration, and I added "install ipv6 /bin/true" to /etc/modprobe.conf to disable ipv6.

So, could this be indeed a Firefox bug? (doesn't seem so, but...)

THis is all I did to fix my problem on FC 10 in Firefox.
"network.dns.disableIPv6" set to true on FF's configuration
I'm a happy camper now.
