Ssh should take care of exporting the correct tunneled DISPLAY if you
specified the -Y option when connecting. However, with firefox you have
to be careful that the same user does not already have a copy displaying
elsewhere. If so, it will try to open a new window in that session
instead of starting a new one. I don't think that's the problem in this
case or you wouldn't get the 'no display' error, but when it does happen
it can be confusing.
