Why won't Firefox install after I've downloaded the latest version? I can't get it to open. I have it on Mac with OSX system. It worked before the storm killed the power but now it won't open up at all, using the same methods I used before.

My power was shut off due to a storm. When I fired up my Mac, the Fox was nowhere to be found.
