I think you need to use -Y instead of -X these days but I've never understood 
which apps care.  Also, firefox is unusual in that if it is already running for 
a user it will try to tell the running copy to open a new window in its existing 
context instead of opening a new one that can be forwarded (but you'd only see 
that if you had X running elsewhere).

What you are trying should work without running X at the console, but you might 
like the freenx/NX client even better.  That gives you a complete remote X 
desktop with very good performance that you can disconnect and reconnect with 
everything still running.  See www.nomachine.com for the client 
(linux/windows/mac) details but you can get freenx from the epel repo.
