I have Microsoft Silverlight installed on my computer, but it is not registering on Netflix via Firefox. Both Silverlight and Netflix are working fine on Internet Explorer, so the only logical conclusion is that there is a problem with in on Firefox. I've uninstalled and reinstalled several times over, even restarted my computer completely after a few of those uninstall and reinstall. Heck, I even tried uninstalling Firefox itself and reinstalling it. I've gotten the same message every time.
