When I am on Firefox, I can't click on the "-"minimize or "x" exit button, I have to right-click in order to minimize or close the screen, also, when I am on Youtube and I click on a video it will start playing fine, but when I try to hit Play/Pause button, skip through video, adjust volume, change quality, or enter full-screen the buttons don't work, the cursor won't even change to a hand. This only happens when I am on Firefox, when I am on IE it works fine.
