In the current release Firefox might be using the HTML5 media player instead of a Flash based player in older Firefox versions.
You can try to set media.apple.mp4.enabled to false on the about:config page to see if that has effect. You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
