Internet Explorer lets you set rules for blocking cookies based on the policies of the cookie-placer.
No major browsers let you track or block beacons without installing extra software known as "plug-ins," as described under advanced steps.
All major browsers offer a "private browsing" mode to limit cookies. Chrome calls it "Incognito." Internet Explorer calls it "InPrivate Browsing," but this option is available only in the latest version, IE8.
It deletes cookies each time you close the browser or turn off private browsing, effectively hiding your history.
"Flash Cookies"
Flash is the most common way to show video online. As with regular cookies, Flash cookies can be useful for remembering preferences, such as volume settings for videos. But marketers also can use Flash cookies to track what you do online.
