So I have no sound in Firefox. I have sound on everything else i.e. internet explorer, music, etc... I checked my volume control mixer and Firefox is not muted and volume is up. I checked all my plug ins and they say they are up to date and enabled. What else can I do?

Upgrade your browser to Firefox 9 and check

See:

You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.
You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.
Current Firefox versions use the plugin-container process to run plugins, so you need to check the volume setting for the plugin-container process.
You will only see the Firefox program or the Plugin Container in the Mixer if you are on a website that plays sound.
