X forwarding in SSH

Should have been more clear. Iceweasel is just a variant of Firefox for linux.

I dont have a spare linux box so I am running puTTY or Bitvise with x11 enabled, on a Windows 10 PC to try and launch my browser on my OSMC Rpi2. This will allow me to do a two step login with my ISP/Hotspot that needs to launch a webpage to complete the login process.

This is what I get when running puTTY.

I first ssh into my OSMC RPi2 and log in.

Then I try to launch my browser…

osmc@SaloonMediaServer:~$ iceweasel

This is what I get back

[1] 2546
osmc@SaloonMediaServer:~$
(process:2546): GLib-CRITICAL **: g_slice_set_config: assertion ‘sys_page_size == 0’ failed
console.error:

console.error:

Any insight would be most welcome!

Thanks
