For me I set this to 1080HD and every time it came up 1080HD which it never did before. But then I noticed I use Logitech options for the mouse gestures just skip back and it stopped working after checking around about config it wasn't that I disabled the extension and immediately all the keyboard shortcuts and gestures started working again and this was every website not just YouTube and it wasn't video related it was anything with the text form. Thought this was kick ass! even though the autoplay thing doesn't work oor drop down menu or any of the other settings work but it does set it to the highest resolution I've ever had. What's done install I'd rather have shortcuts I don't get it but it is what it is thanks anyway
