</p><p>Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See <a href="/en-US/kb/keep-flash-up-to-date-and-troubleshoot-problems" rel="nofollow">this article</a> for more information on using the Flash plugin in Firefox).
</p><p>To disable hardware acceleration in Flash Player:
</p>
<ol><li>Go to this <a href="http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues" rel="nofollow">Adobe Flash Player Help page</a>.
</li><li>Right-click on the Flash Player logo on that page.
</li><li>Click on <strong>Settings</strong> in the context menu. The Adobe Flash Player Settings screen will open.
</li><li> Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. <br> <br>The image "fpSettings1.PNG" does not exist. <br>
</li><li> Remove the check mark from <strong>Enable hardware acceleration</strong>.
</li><li> Click <strong>Close</strong> to close the Adobe Flash Player Settings Window.
</li><li> Restart Firefox.
</li></ol>
<p>This <a href="http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html" rel="nofollow">Flash Player Help - Display Settings page</a> has more information on Flash Player hardware acceleration, if you're interested.
