I have some MP3 files embedded on my website. When I browse to the site in Internet Explorer, the files show up complete with controls (play, pause, etc.). For the longest time, they've also worked in Firefox but now that I have upgraded to Firefox 9, the controls disappear. The files play properly if the autoplay is enabled, so the plugin seems to still work. Just no controls. So I downgraded back to Firefox 3.6 and presto, the controls show up again. I tested with other extensions (.wav and .ogg) and they all have the same issue with the controls not being visible in FF9. Any ideas?
