Kiosk mode on Firefox just like Chromium on Linux?

Question

I have the following script:

#!/bin/bash

xset s noblank
xset s off
xset -dpms

unclutter -idle 0.5 -root &

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' /home/pi/.config/chromium/Default/Preferences
sed -i 's/"exit_type":"Crashed"/"exit_type":"Normal"/' /home/pi/.config/chromium/Default/Preferences

/usr/bin/chromium-browser --force-device-scale-factor=0.90 --noerrdialogs --disable-infobars --kiosk localhost &

done

It does the following: It opens the browser on FULLSCREEN, and it disables the input of some keys like F11, along other things. So, the screen basically becomes just the browser content itself, without any visuals on it - It runs on fullscreen and it's difficult for the user to disable it, close the browser, etc.

My question is: Is there anyway i can do the same thing but on Firefox? I tried using the -kiosk option as this documentation said but it did'nt work.

Before someone says it: I only have Firefox installed on this OS and want to do this using Firefox, and not Chromium - So "Just uninstall firefox and install Chromium" isnt a solution...

OS Version: Ubuntu 22.04

Thanks in advance!
