FReepers are intelligent but not clairvoyant. Which browser are you referring to?
Keep in mind that plug-ins/add-ons/extensions are considered part of the browser by web sites & developers but from a user perspective these third-party items must also be kept up to date. Flash and Java are notorious for frequent - but often necessary - updates for compatibility, security, etc.
Ninite.com is an excellent one-stop shop to automatically download/install these free apps and add-ons without having to wade through the installation process (i.e. no toolbar pitches, no clicking next, etc.).
I think it’s an OS issue, just tried it directly from a live Ubuntu 10.10 CD on the Firefox browser that’s included and it still doesn’t work.
Oh well. Guess they don’t iHeart listeners.
