You’ve probably heard about cookies before, but maybe you don’t understand exactly what they are or why they’re so important. You can get by without knowing much about them, but if you want to best maintain your privacy while browsing the web, learn what cookies are.
In short, cookies are files created on your computer when you visit a website. These files are meant to store information that must be available from session to session — such as login data — and aren’t inherently harmful. However, they can be used in harmful ways like tracking your web behavior.
What we recommend doing is to allow first-party cookies (which are cookies set by the actual site domain that you’re visiting) and disallow third-party cookies (which are cookies set by other domains, like advertising networks).
Note: Some sites might need third-party cookies to operate properly. For example, online banking sometimes require these cookies for user verification.
