Internet Explorer flaw lets websites track your every mouse movement, and MS refuses to fix it
If you don’t want to be tracked, you do have options available. Firstly, you can switch to a different browser. Chrome or Firefox are fantastic options, and they aren’t affected by this flaw. Secondly, you could turn off JavaScript in IE. While this does hinder the usefulness of most modern websites, it will prevent IE from passing on your mouse movements. These aren’t optimal solutions, but Microsoft has given us little choice in the matter. Unless it steps up and patches this flaw, it just isn’t safe to use IE with JavaScript turned on.
