Some Internet cookies are helpful, some are harmful.
These three tools help you distinguish friend from foe. Often cookies make your browsing experience smoother and more personal. For example, cookies allow you to jump to a New York Times online article without having to log in each time you visit, and they allow an online shopping cart to remember the items you have selected for purchase. But other cookies are used to spy on your browsing habits and feed information about you to marketers. A cookie-management program can help you sort the good cookies from the ones that leave a bad taste in your mouth.
