Mozilla developers have blocked a Firefox plugin that was quietly pushed out by Microsoft, saying that it presents a security risk. (...) On Tuesday, Microsoft warned that Firefox users who have not applied a recent Internet Explorer patch were vulnerable to a "browse-and-get-owned attack" because of a bug in the Microsoft .Net Framework Assistant add-on.
To protect users who may not have installed Microsoft's patch, Mozilla is automatically blocking two add-ons: the Microsoft .Net Framework Assistant and a related plugin called the Windows Presentation Foundation. (...) "Microsoft agreed with the plan, and we put the blocklist entry live immediately."
