YouTube uses the HTML5 media player and not the Flash plugin in current Firefox versions.

You can check that via the right-click context menu in the player area. The Flash player always shows the Flash version that is used. You can open the YouTube test page via "About the HTML5 player".

Are all features available and enabled?

You can 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.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
