(Newbie:) Why use privoxy?

Actually Keith, that is not the case with Firefox. Martin is correct.

Firefox  can do remote DNS resolution, which is done through the SOCKS
proxy.  This  does  NOT leak DNS requests, and they are passed through
tor.

Just  surf  to "about:config" and find remote dns, and make sure it is
set  to  true.  Then  set  up  your  machine to use a SOCKS proxy with
localhost as the IP and whatever port you set in the torrc.
