I was getting annoyed at YouTube for not letting me use fullscreen anymore, then I looked into it and found it was sort of a Sea Monkey issue. Also found this add-on installed it. After installation all I had to do was reload the open YouTube page I was on and full screen worked perfectly. Total, complete edge to edge full screen, without even a mouse pointer. If you move the mouse, the video title and sharing options superimpose at the top, and player controls at the bottom. They fade out if you don't use them. Don't know about the comments above, but this about as complete functionality as you can get, in my experience
