يعمل لكن يختفى عن استخام شخصي اخر يختف من الصفحات

This extension doesn't show the player timeline as it shows in the pictures I use it for tutorials so to take the maximum amount of the screen for the video instead of having the taps and the youtube layout to take out of that space as I use it for tutorials I wish I could rewind and go back to where I need repetition!
