Delete Cookies
When you use a web browser, cookies are stored on your computer. The server on the other end of the connection reads the cookie file. Most of the time, cookies are a beneficial thing—without authentication cookies, you'd have to enter usernames and passwords every time you visited a website, on every page. Cookies also allow online shopping carts to function without losing all of your items prior to purchasing.
Cookies are generally beneficial, but they can also monitor you. Control a little portion of your online privacy by blocking, removing, and allowing only specific cookies. You should also configure your browser to remove all cookies at the conclusion of each session so that anyone who uses the computer after you does not find your personal information via autofill. Deleting cookies also prevents websites from displaying those obnoxious tracking adverts.
