Want to see how private you are on the Internet?  Visit Panopticlick, at https://panopticlick.eff.org/, and see just how much information your browser reveals to the Web sites you visit.  Each and every computer has a browser fingerprint based on one or more points of identifying information, from the exact version of the browser that you use, to the fonts you have installed, to the resolution of your screen.  Web sites use these details to enhance your browsing experience, but if a Web site stores this information about you, it can be effective at tracking where individuals go on a site.
