Delete cookies in Chrome & Firefox on Windows & Mac

The quickest way to delete cookies is to eat them. But cookies in the online world are small data files websites put on your computer to store bits of information. They’re used for things like keeping you logged into a website or storing items in a shopping cart.

Cookies will not damage your computer, but they can compromise your privacy. Not all cookies are used for good purposes. Many sites use cookies to track your online activity. Ad servers may send cookies along with ads displayed on websites to identify viewers and track their browsing habits. This information is used to push relevant ad content to us whether we like it or not.

Some cookies can tie your online activities to your real-world identity, thereby compromising your privacy. You can delete cookies stored on your computer automatically and manually, and we’ll show you how in Chrome and Firefox on Windows and Mac.
