Users on Mozilla Connect have requested a "tablet full screen mode":

Instead of adding a new full screen button or setting, maybe we could just hide the system status bar when the user scrolls the page, like we do for Firefox's own address bar. In fact, Safari on iPhone (but not iPad) and Samsung's browser ("Internet") on some Android devices (my Samsung Galaxy A32, but not my Moto G5) do exactly that, but only in landscape orientation.
There is a risk that malicious web pages might mimic the system status bar without needing to trick the user into clicking Firefox's full screen prompt.
We would need to make sure that users could escape the "system status bar is hidden" mode if a web page prevents the user from scrolling (maliciously or otherwise). That might be way Safari and Samsung Internet only hide the system status bar in landscape orientation.
Another user reported this feedback de on the Play Store would be useful to have a feature like this in fact.
