Firefox crashes, usually on video content

Most of the time when I interact with a video content (YouTube, 9gag), the Firefox will crash. At the beginning it was just the tab that was crashing and I was able to report it, but now it is the entire browser that is closed by Windows without the crash reporter window opening.

I have both Firfox and Firefox Developer Edition installed and they both behave the same way.

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.

Thank you for your prompt reply. Since these crashes I have updated both FF and Flash. I have managed to get some another report, after the HW acceleration for Flash is switched off:
