You can toggle fullscreen by pressing F11. I would suggest you use Google Chrome or Firefox (preferably Chrome) - Microsoft lags far behind everyone else in terms of browser capabilities.
I am having a problem when I play a video on Netflix and youtube, the screen will stay in full screen. Is there a way to fix this problem?
f11 for full screen does not work in Microsoft edge. I have tried pressing f11 but nothing works. I don't think there is a code to exit full screen when switch between full screen and normal size window for Netflix and YouTube.
