JPlayer not playing only in Firefox using JSONP

Question

I am using JSONP to wrap the JSON response. Works fine in Chrome, IE and Safari.

The MIMEtype from the PHP script I am referencing is sending Content-Type:text/html

which may be the issue as I found this answer

changed this

$(document).ready(function() {


    $.getJSON("http://www.freeenergymedia.com/getxml2.php?callback=?", {},function (json) 
    {

        new jPlayerPlaylist({
            jPlayer: "#jquery_jplayer_1",
            cssSelectorAncestor: "#jp_container_1"
        }, json, {
            swfPath: "js",
            supplied: "mp3, ogg",
            wmode: "window"
        });
    })
});

to this

 $(document).ready(function() {


        $.getJSON("http://www.freeenergymedia.com/getxml2.php?callback=?", {},function (json) 
        {

            new jPlayerPlaylist({
                jPlayer: "#jquery_jplayer_1",
                cssSelectorAncestor: "#jp_container_1"
            }, json, {
                swfPath: "js",
                supplied: "mp3",
                wmode: "window"
            });
        })
    });
