On certain websites with Flash based web players my whole of Firefox lags like crazy. I have been trying to fix this issue for a while to no avail (Tried resetting, re-installing, etc.) It mostly happens when I move my cursor over the Flash player. After I move my cursor so somewhere else on the webpage (a non-Flash part) it start flickering between the default cursor and pointer (clicking finger icon)

Now today I decide to uninstall the Flash application from my PC and reinstall it. After I uninstalled the Flash player suddenly I have no stuttering issues on Firefox anymore! But of course some other Flash related application do not work anymore.

When I re-install the Flash player it goes back to stuttering and lagging. When I disable the Flash player plugin in about:addons the stuttering is gone.

Any help with this issue would be greatly appreciated. It has been bugging me for so long now that I have to use Chrome to visit certain websites...

Hello,

Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See this article for more information on using the Flash plugin in Firefox).

To disable hardware acceleration in Flash Player:

  1. Go to this Adobe Flash Player Help page.
  2. Right-click on the Flash Player logo on that page.
  3. Click on Settings in the context menu. The Adobe Flash Player Settings screen will open.
  4. Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel.

    The image "fpSettings1.PNG" does not exist.
  5. Remove the check mark from Enable hardware acceleration.
  6. Click Close to close the Adobe Flash Player Settings Window.
  7. Restart Firefox.

This Flash Player Help - Display Settings page has more information on Flash Player hardware acceleration, if you're interested.

Does this solve the problem? Let us know.
