I didn't get around to trying Google, but I found a solution:

http://www.linuxquestions.org/questions/blog/tw001_tw-27416/slow-dns-resolution-in-mozilla-and-firefox-129/

Basically, open a tab to about:config, search for network.dns.disableIPv6,
and set it to true.

Blisteringly fast DNS lookups. :-)
