Sometimes, the video or audio content in a web page cannot be properly downloaded and displayed in Firefox. A required plugin may be missing, outdated, blocked, in conflict with another plugin or extension, or the content may be blocked for some reason. This article will help you solve these problems.

Thanks for that, but unfortunately, it hasn't corrected the issue for me. Just an embedded MP3 won't play (from my own website.) Of course, it play on Firefox on my Desktop mac. I can't seem to get this to work or find a solution....

Maybe you need to install or enable (Tools > Add-ons > Plugins) some plugins to be able to handle more types of media files.
