So whether its twitch or youtube or any other site that uses one, when I have an 'html5' player there's a couple pixel border on the top/bottom of the screen that is kind of jarring for it to be there and keeps it from feeling like true fullscreen. I was wondering if anyone knew how to get rid of it, or if it was even possible. http://i.imgur.com/2g6hBU6.png The image above is a cropped example of the border as it appears at the top of the screen. Tried including it as an added image but it didn't want to upload properly :/ The color of the border seems to relate to the current firefox theme (I use walnut so in this example its like this orange-brown which makes it all the worse for darker videos) Thanks in advance for help
