[Plugin: oEmbed HTML5 audio] Does Not Appear in Firefox 14.0.1 when W3 Total Cache Active

I installed this plugin to replace Audio Player, which has not been updated in 2 years, and was not playing all files (file not found message).

oEmbed HTML5 audio works fine for me in Chrome, Safari and IE 9 with W3TC page caching active, but not in Firefox, so I had to disable W3TC page caching for the page with the MP3s.
