Be aware though that Firefox seems to try to be clever. I use this technique from home to access intranet web sites by first making an inbound SSH connection. However, if I already have Firefox running locally, then try to start a remote Firefox via the SSH connection, it seems to want to action it via the local Firefox instance
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.
