ff starts flickering the screen black when I click play on videos imbedded to sites. Started roughly a week ago. Makes everything else slow too :(
Now when I click on the url entry top part of the screen it is very sluggish and often does not flow well. The screen flickers parts black when I try to play a video on facebook and just keeps flickering while it plays the video. When I maximize and minimize I can see the parts of the screen go black which is also my background color.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
You can check if there is an update for your graphics display driver.
