Mac Firefox, latest updates, all add-ons are current and working. Audio specifically will not work on YouTube Videos using Firefox browser, but works on Chrome and Safari. Other videos work fine on Firefox so issue seems specific to YouTube and Firefox.

Check that you have the latest plugins for the browser.

All the add-ins are up to date. One difference I notice is that FireFox uses QT and the other browsers use Adobe Flash. QT Plugin 7.7.3 is current and up to date. Shockwave Flash 16.0.0.235 is also listed and is up to date.
