Please try two things, please clear the storage for the flash plug in by right clicking where the video should be and clicking "Global settings" and navigate to storage. Clear the stored data and restart Firefox.

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.

You can also 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.
