Thank you for the explanation. That is seriously broken behavior. I'll try
installing another browser. The scenario this happened is I have a firefox
session running on a remote machine with X forwarding because it has a web
server on it that is not accessible outside the LAN.

On my local system I have a tor instance running and firefox configured with
torbutton and privoxy. Once I use the webserver on the remote machine I
can't get to my copy of Firefox that has access to tor on the local
system, or if I start the local copy of firefox with tor I can't get to the
webserver on the remote system.

I'll post something on the tor list and maybe they can help the firefox devs
pull their heads out of their ass.
