Screen flickering in Firefox

I have Firefox 16 installed. For some reason, my screen flickers in this. A Firefox rep said disable hardware acceleration.

Well, that rep needs to know first hand that it didn't work. My screen flickers a lot. I don't want to change browsers.

How do I fix this? It's an annoying bug.

If it was not hardware acceleration causing that, maybe it is an extension doing that. Does the flickering happen in Firefox safe mode?

Are there special conditions like plugins being used when that flickering happens?

You can check for problems caused by recent Flash updates and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin
  • downgrade the Flash player to version 10.3 or 11.2
