Run firefox across ssh?

[S.Bob]

All;

I seem to remember way back in the day we used to ssh to a server, set 
our local display on that connection and then run a web browser FROM the 
ssh target but display the web browser on the source machine.

I think we used to do this:

ssh -Y target_machine

export DISPLAY=:0

$ firefox &

I have a mac, I can ssh to it, I want to run a web browser FROM the mac 
but displayed on my Fedora 31 laptop.

I tried this:

ssh -Y mac_ip

export DISPLAY=:0

$ /Applications/Firefox.app/Contents/MacOS/firefox

But no joy

Thoughts? Is this possible?

Thanks in advance

I think the problem is OSX does not use X11 as its windowing
system so the fedora box cannot draw it. With that said, good old vnc
will work just find.

You do not want to export DISPLAY, either the ssh -Y set it right or
it did not.  In either case :0 is usually the monitor directly
connected to the device so that will probably never be right for a ssh
connection.

The MacOS display system is not based on X, so this won't work out of
the box. I believe you can install an X server from the Mac app store
which should allow it to work.

Even if you install an X server, the native Firefox is not going to use
it to render.  You may be able to compile a version to work but it will
take more than just having X.

True, I was (mis)reading the situation as the other way round, i.e.
displaying a remote Firefox session on the Mac.

Vnc is probably the way to go.

Do not fiddle with $DISPLAY. "ssh -Y" sets $DISPLAY for you, to a 
display which is tunnelled _back_ over the ssh connection to your local 
machine's X11 server.

You do need the "xauth" programme installed on the Mac in order for ssh 
to arrange the access token, but that is easily installed with HomeBrew 
or MacPorts or via the Mac XQuartz stuff.

And WRT to the various misinformation in many other posts in the thread:

- the native Mac desktop isn't X11

- there's a well supported X11 system available which can be run on Macs 
  (XQuartz) which runs as an app, so you _can_ run X11 programmes 
  locally displayed on a Mac

- both of these things are irrelevant to your "ssh -Y" question
