解决FireFox不能Debug Silverlight程序的问题

最近在做一个Silverlight的项目，一直用的是FF，却发现默认情况下FF无法调试Silverlight。困扰了我n久，今天总算是搞定了~

贴出来跟大家分享下：

Try these steps...

1. Type "about:config" into FF's address bar
2. Accept the warning (if applicable)
3. Search for the entry "dom.ipc.plugins.enabled.npctrl.dll"
4. Change its value from "true" to "false" (double-click)
5. Restart the browser
