Run firefox within a Linux chroot jail in FreeBSD 13.1

I have managed to install a Ubuntu chroot jail within FreeBSD 13.1. However, I need to run Firefox from it to launch Jupyter Lab from a python virtual environment within the chroot subsystem. I was wondering if I could use the FreeBSD Firefox from the subsystem. Nevertheless, I installed Firefox on the chroot subsystem and when tried to run it I gen an error as below.

(newEnv) schroter1@SCHROTER:~$ firefox No protocol specified Unable to init server: Broadway display type not supported: unix:0.0 
Error: cannot open display: unix:0.0

Would anyone be able to help me in this regards. Thanks & Best Regards Schroter Michael
