Firefox glitching/pixelating at top of screen

Firefox has been my default browser forever but suddenly has started glitching! It will work for about 10 minutes but then the glitch happens and all of the top of the screen loses its text and turns into black/white color boxes that looks pixelated and the whole program freezes. In the picture posted, the glitching continues down the right side of the screen too. If I quit Firefox, it starts up fine again (with all browsing tabs lost) but then the error will occur again in a short while.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.
