Yeah, like others have said it is most likely some extension you are
running. Maybe google toolbar, yahoo toolbar, something of this nature
that interacts with each page? I tried watching Torbutton and
socks-only and got no DNS leaks w/ ff 1.5, no matter what my timeout
settings were. I did get a few "Try Again" timeout messages from
firefox, but no leaks.
