Most/all the main web browsers in use support kiosk mode, you’ll just need to search around for how to do it. This should get you going for Firefox

Am not too sure how to get out of kiosk mode afterwards, maybe test it when you don’t have anything else running just in case.
EDIT: If you need to run kiosk mode for a specific amount of time as you say, you’ll probably need to also run a scheduled cronjob or similar to maybe kill the web browser at a specific time. I’ve seen kiosk mode for a few web browsers but they don’t usually have an option to set them for a specific amount of time.








Brent Spiner does often appear in random roles here and there though he’s slowed down more recently. He was the wacky scientist guy in the Independence Day movies for example, LOL. He was also great in the Outcast TV series but I get the feeling it wasn’t as well known.
