This just randomly started earlier today. When I load a page, at first, the page will be completely black, and then it will load up. However, if I start to scroll on the page, it will flash to black again, and then I have to scroll up and down a few times to get it back. I tried restarting Firefox and my computer.

Does that happen with Firefox safe mode? It might be an extension causing problems, or it might be hardware acceleration.

Try to disable hardware acceleration in Firefox.
