That can be avoided by using "firefox -no-remote" as your command to
start Firefox. While the name of the option sounds counter-intuitive,
think of it as your command to run a new instance of Firefox, as opposed
to remotely controlling an already running instance (such as loading a
new address in a tab).
When you run Firefox, you don't actually run it directly, you're calling
its handler program. That handler is making a decision about how to use
Firefox.
See: man firefox
I've done this before. Essentially:
1. Ensure "X11Forwarding yes" is set in the REMOTE system's
/etc/ssh/sshd_config file and make sure sshd has been restarted
to read it.
2. Run "xhost +" as root on the LOCAL system to permit everyone
to make connections to the LOCAL system's X server.
2. "su - unprivileged-user-name" on the LOCAL machine.
3. "ssh -X user@REMOTEHOST" to log into the REMOTE machine.
4. Verify you have a DISPLAY variable set by doing
"echo $DISPLAY" on the REMOTE machine. You should get a value
like "localhost:10.0", indicating you have X forwarded.
5. Run "firefox" on the REMOTE machine. The display should pop
up on your local machine.
This has worked for me for a long time.
