Why does my Firefox lose its ability to do DNS lookups?

Every once in a while (time between failures ranges from 1 hour to a few days), Firefox on my laptop suddenly and permanently (until reboot) loses its ability to do DNS lookups. Every page comes up with "Firefox can't find the server at www.foo.com." Other apps (and computers on the network) continue to work fine. It seems random; I haven't been able to correlate it with anything else on the machine. Closing and restarting Firefox doesn't restore its DNS lookup ability, but rebooting does. Googling only turned up the advice to disable IPv6, which didn't help. I'm currently running Firefox 22.214.171.124 on a Dell Inspiron 8600 running XP Home, but it's been an issue since at least 1.5. My only extension is Better Gmail, and I've tried disabling all extensions in the past. I'm at my wit's end - do any geniuses here have a clue?
