Hide min max close buttons

I am trying to setup a kiosk using firefox and have it coming up full screen without any issues but the min max and close buttons are still at the top of the screen when you move the mouse up. I need to hide or disable all those buttons so no one can close firefox or get to the desktop. I am exhausted from looking at options. Anyone have any ideas? I am not a programmer either.

Mozilla offers an add-on to do that

And this source

"If you are using full screen mode and have those buttons on the Navigation Toolbar then you need to use this code.

#window-controls { display:none!important; }  "

Thank you VERY much! That seems to be the ticket! Now I can do the other 21 computers :)
