This seems to be happening more and more frequently. I am running Firefox 23.0.1 on Mac OS 10.8.4. It even happens on the Mozilla support page. It used to happen every so often; now it happens at least 50% of the time.

Try to disable IPv6 in Firefox (network.dns.disableIPv6 = true).

You can try to reset (power off/on) the router.
