Torbutton does different things depending on your version of Firefox.

On versions less than 1.5.x -- the ones that don't support
socks_remote_dns -- it sets every proxy it can find, because if you
leave any of them out, the browser will default to your socks proxy and
broadcast the DNS resolve as it does so.

On versions that have socks_remote_dns, we're in better shape. Torbutton
automatically sets that, so now when things default to your socks proxy,
it's still safe.

I just updated the FTP FAQ entry:
