Firefox Blank Page or Not Working

I use Firefox occasionally for certain things. One laptop would not run Firefox properly. Some versions would show the original site but no left click response on anything. Some versions would show a totally white (blank) page.

Here is the fix:

1. Hold the shift key down when starting Firefox.
   (A message will display asking if you want to start in safe mode. You do.)
2 Now go to options > general > performance

 You will not see the necessary option until the box below is unchecked.

Once unchecked the necessary option will appear. uncheck "Use hardware acceleration"

Now Firefox will work.

This hardware acceleration problem can occur in Chrome as well. The missing link is how to start Firefox in safe mode.
