Yes. The first arg to #'start-process is just a name to give to the
process so it can be more easily identified, it doesn't have anything to
do with the actual running of the started process.
I've not witnessed the behaviour you're describing, not in any version
of Firefox from 1.0 to the current 3.0 betas.

I have no objections if you want to make this change, Eli, but there's
not much point in doing so.

OK, this appears to be the case for Linux now as well, but I'm fairly
sure it wasn't always like that in earlier versions of Firefox. And
starting Firefox with `-remote' when there is no running instance gives
you an error. Hence, the sentinel.

I've not witnessed this behaviour either. And I'm not sure which of
Firefox, Emacs, MS-Win, or some combo-special, that is to blame.

Apparently so. :-)

> Any objections?
Yes. You would also need to remove the `-remote' arg in
#'browse-url-firefox. Of course, you'd only make these changes if I'm
wrong about how earlier versions of Firefox handle starting with
`firefox http://some.site/' when an instance of Firefox is already
running (for non-MS platforms).
