Firefox disables Microsoft Plug-in

the recent Microsoft patch, which included 13 patches addressing 34 separate vulnerabilities in the Windows operating system, included a patch for the .NET Framework as well as two plug-ins for the Firefox browser called “Microsoft .Net Framework Assistant” and “Windows Presentation Foundation”, which got installed silently if you had Automatic Updates turned on.  After discovering the vulnerability in this plug in, today Mozilla, with the knowledge and consent of Microsoft, disabled this plug-in from Firefox.  You might see this screen pop up the next time you open Firefox:



Notice that the plug in is still installed on your system.  If you want to completely remove it, go here for a removal tool.
