In February, Microsoft quietly installed .NET Framework Assistant (ClickOnce) Firefox Extension. This extension is a bad idea because of what this could do.

This update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for websites to easily and quietly install software on your PC. Since this design flaw is one of the reasons you may’ve originally choosen to abandon IE in favor of a safer browser like Firefox, you may wish to remove this extension with all due haste.

As you see, this is a way to make Firefox less secure and almost like Internet Explorer.   We’ve seen the problems with all the [intlink id=”2946″ type=”post”]Malware exploits[/intlink] that people have used in the past.   If you want to uninstall it, well you can’t.   Microsoft as went out if its way to prevent users from uninstalling.    Here is what Brad Abrams talked about on his blog:

[ad]We added this support at the machine level in order to enable the feature for all users on the machine.Seems reasonable right? Well, turns out that enabling this functionality at the machine level, rather than at the user level means that the “Uninstall” button is grayed out in the Firefox Add-ons menu because standard users are not permitted to uninstall machine-level components.

If you went to your Addons Menu and then to your extensions tab you would see that the uninstall button is grey out. You can disable it but you can’t uninstall it. It looks like Microsoft has sent out a patch to let regular users uninstall this addon(KB963707).

I am really surprised that Microsoft did this little stunt. I would of expected more from Microsoft, but to their credit they did this for a reason to allow users who don’t use IE8 but Firefox , to be able to use the .net Framework but this plugin makes browsing just unsafe. Don’t forgot about the [intlink id=”1010″ type=”post”]MobileMe apple installed on Vista[/intlink] without your knowledge. Microsoft and Apple have both had problems but this is very disturbing.  This patch they are letting people download to fix the problem doesn’t mean much because it hasn’t been sent out to the Auto updates and requires people go download it manually.  So Microsoft believes if you don’t know, it won’t your.
