The Advantages & Disadvantages of Deleting Internet Cookiesby Kevin Lee
If a site relies too heavily on cookies, problems can occur. For example, if a website expects your computer to contain a cookie that has login information, you may not be able to log in to the site if you delete your cookies and the site's developer provides no alternate method of logging you in. Cookies are also tied to specific computers. If a site stores cookies on your home computer, that site won't remember you if you visit it using your work computer. When you share your browser account with other people, they can get an idea about the sites you visit by checking the browser's cookies unless you delete them.
Some people may not mind websites remembering their visits while others might not want anyone tracking them. If you are concerned about privacy, you have the option to review your browser's Help documentation that explains how to disable and delete cookies. You might also consider disabling third-party cookies instead of disabling them all. A third-party cookie is one that an advertiser might place on a site you visit. It may also remember information about your browsing activity and store it on your hard drive. Your browser's help documentation can show you how to disable these types of cookies.
