Howtogeek shows you how to use the Tracking Protection List in IE9

Most websites use adverts as a form of income, and there is nothing wrong with this. The problem comes when the adverts on someone’s websites start tracking our browsing habits. You might be wondering how this works, well when you go to a website that has to request anything (an image, a cookie, HTML, a script that can execute) you have can be tracked. Most of the time this is done with something called a third-party cookie, in this method the company that provides the adverts dynamically store a cookie in your browser. When your browser sends an HTTP Get request to the web server hosting the adverts, the webserver will respond with a HTTP Response packet, the packet will have a Set-Cookie attribute attached to it that will tell the browser to store the cookie. Now when you go to any site that gets adverts from that ad company they can track your browsing. They can use this footprint to better target adverts at you.
