Microsoft Silverlight does not install on Firefox 5. It is installed and works with Internet Explorer 9. I have uninstalled and reinstalled it but it still says it's missing when I try to play a video online. I am running Windows 7, 64bit on a Sony laptop

unable to play video on www.iranibash.com, it says that MS Silverlight is not installed. But it is installed and works with IE9. I have uninstalled and reinstalled the plugin but it still says it's not installed in Firefox 5. When I try to install it, it says installation failed.

Forgot to mention that it won't play Netflix either.
