my screen encompasses the entire view. no top tabs or windows tabs all of the sudden
I need help putting my screen back to normal!!!!2
Possibly it's "full screen".
There are two kinds of full screen:
(A) Full screen triggered from page content, for example, a video player. Use the Esc key to cancel this kind of full screen.
(B) Full screen built into Firefox. Use the F11 key to turn this on and off.
Do either Esc or F11 help?
