Why can't I find a way to turn hardware acceleration off?

In advanced settings, general panel, I am trying to turn off hardware acceleration, but the panel is totally unresponsive--greyed out, I guess is one way to express it. My objective is to stop my Silverlight plugin from going unresponsive all the time. I'm trying to follow the steps outlined but find the Firefox pages/panels etc. unresponsive.

I'd suggest that you first update your graphics driver, Upgrade your graphics drivers to use hardware acceleration and WebGL.

If that fails to correct your problem (It's always better to have Hardware acceleration turned on than off), type about:config into the address bar, press enter, and then set layers.acceleration.disabled to True

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
