[Plugin: MediaElement.js – HTML5 Video & Audio Player] Plugin not working in Firefox

same thing here, chrome is working perfectly but in FF, it just plays with a black screen.

anyone know where the error is?

Same thing here: the plugin stopped working in Firefox – which is funny as I remember having tested it a few months ago, without any FF issue then.

For the time being I suggest as alternative the Flash Media Playback plugin. It isn’t HTML5, rather Flash, but at least works beautifully.

Latest update… stopped working completely now in FF. I will be ditching this

BTW that’s just one drop in the ocean – yesterday I’ve found jQuery UI plugins breaking apart in the latest Firefox upgrade. Something goes really really wrong in FF 3.6.13.
