I go to multiple websites that contain embedded media, such as billburr.com, tunein.com, and forums where members embed media from sites like YouTube. When attempting to access or use that media, using the available play, stop, pause, and volume control buttons, FireFox doesn't respond. For example, If I'm on billburr.com and attempt to play the podcast, I can click the play button over and over again and nothing will happen. The play button lights up like the site realizes I'm clicking it, but the media will not play, at least not the first time. I might get it to work after several fast clicks. However, if I need to pause it, I have the same trouble. These sites work perfectly in IE 9. I've already started FireFox in safe mode, but encountered the same problem. Has anyone seen this?
