Recently, I visited the China website for listening some songs using Firefox 7.0, and found that I need a plugin called Moonlight, since I am using Linux.

So, this Moonlight is the Silverlight alternative for Linux. If you visit the website such as 1ting.com, then this is what you need.

However, Moonlight xpi file is not compatible to Firefox 7.0. Thus, some modifications towards the xpi file is needed. If using Arch Linux, it is available in AUR (submitted by me).
