The usual issue with firefox is that if you have an instance running
and attempt to start another instance (perhaps with a different
DISPLAY) it will instead tell the running instance to open a new
window.  I've only seen that in the reverse situation - where the
remote host has the other copy and you don't see the new window and
I'm not sure it makes sense for what you describe.   In any case,
using freenx and the nx client is a much nicer way to do remote GUI
