Mozilla plans to integrate kiosk mode functionality in version 71 of the Firefox web browser that users of the browser may launch from the command line.

Mozilla Firefox accepts the same parameter as Google Chrome to launch kiosk mode. Just load Firefox with --kiosk as a parameter to launch the browser in that mode. You may also append a site URL to the command, e.g. --kiosk https://www.stackoverflow.com, to have it loaded by the browser directly.

You can download the Firefox v71 here: https://www.mozilla.org/en-US/firefox/71.0beta/releasenotes/ (currently it is still in beta version)

This is my .bat script when the computer started:

start "" "C:\Program Files\Mozilla Firefox\firefox.exe" --kiosk --private-window https://www.stackoverflow.com

Note that in --kiosk mode, you cannot use window controls, Esc or F11 to exit kiosk mode. The only valid option at the time is to press Alt+F4 to close the entire window.
