Crunchyroll Fullscreen Keeper per mmese

Keeps fullscreen, even after autoplay. Click on a show, click on the toggle button, and press F11, and enjoy your binge. Due of some code peculiarities, you have to press the extension a few times on the toolbar for the menu to pop up, unless it is in the overflow menu, in my experience. This is a port of the addon of the name "Crunchyroll Full Screen, All The Time" on the Chrome Web store, made by pop37 corn. All rights to the code go to the original author, as I did not create the code, I just edited it to make it compatible with Firefox. If they would like this taken down, I will take it down.
