I have downloaded Firefox Aurora and after opening the browser any time I touch a portion of the screen I get a blinking black background. As well, the search bar is missing when screen is minimized, same action when typing in the search, clicking on home or options button, scroll bar or any other section of the screen. I just get fade out in the background. It previously happened when I downloaded Firefox a few days ago, uninstalled the product and reinstalled same results, again uninstalled and installed Aurora same thing happening. I am running windows 7 don't think that should be an issue especially since it is compatible with the system.
