Windows update silently added "Microsoft .NET Framework Assistant and ClickOnce support" as a Firefox extension. According to Wikipedia, "ClickOnce enables the user to install and run a Windows application by just clicking a link in a web page" which doesn't sound too reassuring. huh.gif

Furthermore FF's uninstall button is disabled, but sites like http://support.mozilla.com/tiki-view_forum...parentId=265132 or http://wyday.com/blog/2008/how-to-uninstal...t-from-firefox/ suggest ways to get rid of it anyway.
