“Cookies” have been the subject of some cybersecurity-themed scares. You may have heard that cookies on websites can track your browsing habits and send them to the creator of the cookie, or some variation on why cookies are bad. The truth, however, is that cookies are harmless (and helpful), and it doesn’t matter how many cookies you have or how often you delete them. If you’re going to worry about anything on your web browser, your browser history is a good place to start. Clear it every now and then.
