I started firefox and it said it was downloading update. After the download the screen came back with the top half blurred and an open black box in the middle. What happen? Is there a fix?

This could be caused by an incompatibility between Firefox 33 and your graphics card/chipset drivers. Please disable hardware acceleration as a temporary workaround. Step-by-step directions in this thread: https://support.mozilla.org/questions/1025438

Does that work?
