Which iHeart station doesn't work? I just tried http://www.iheart.com/#/live/1465/ and it plays for me in Firefox 9.0.1. I'm using the latest Flash Player 11.1 r102 (on Windows 7) so you could try updating Flash. See Flash Plugin - Keep it up to date and troubleshoot problems for update help.

If updating Flash doesn't help or if you want to try something else first, see Fix common audio and video issues. You can also try iHeart's help forum at http://getsatisfaction.com/iheartradio

Seems unlikely that flash is the culprit for the following reasons. Iheart works fine with internet explorer (same stations). I accept all updates on Flash. I am using Vista, but again, explorer has no problem whatsoever.

Internet Explorer uses an entirely different ( Active-X) Flash Player, so don't go by that. Firefox uses a separate Flash Player Plugin. Your Flash plugin (Shockwave Flash 10.3 r181) is outdated, as you can see by going to Mozilla's Plugin Check page.

If you don't want to try updating Flash then that's fine. try my other suggestions:

• see Fix common audio and video issues

Ok Alice. You were completely right and I am an idiot. Updating flash fixed everything. Thanks a million. I love Firefox and did not want to change. Now I don't have to. Judd Meyers

Hey, that's great! Thanks for posting back that updating Flash fixed it.

(I'll mark my first post as solving the problem).
