Don't know if this is a Firefox or Adobe problem. Suspect Firefox, because as I play on the site, the game gets slower and slower, and eventually freezes, demanding a CTL/ALT/Delete exit. I've refreshed my Firefox browser, but it too made no difference to the performance on the site. Any help would be nice.

Is this with all games, some, a few? +++++++++++++++++++++++++++++++++++++++++++ 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.

I would first go and update your Videocard Drivers.

Then go and download Malwarebytes Anti-malware Free and run it through 1 scan, then remove it or whatever.

In firefox type in "about:support" in the URL bar and you will have a stats page. Under "Multiprocess Windows" it should be set to "Enabled" and under graphics "Compositing" should be "Direct3D 11"
