How to enable cookies in Mozilla Firefox?

Mozilla Firefox is a free, open-source internet web browser known for being fast, private, safe, and secure. Like other Internet browsers, Firefox collects cookies from websites to help remember your individual website preferences.

Cookies also keep you signed in to certain websites, which saves time. If you’re disconnected from frequently used websites, or websites keep forgetting your settings, Firefox’s cookies may have been disabled.

Cookies are also used to track your behavior as you browse online on different websites. A classic example is this, you browse online to buy a product and then this is repeated to you in the advertising banners of other sites. These are called third-party cookies and many users decide to disable them to prevent their tracking.

By default, this feature is already enabled, but there are situations where you need to adjust the cookies yourself. It is important to know where they are and how to activate them. In this text, we will show you how to configure cookies in Mozilla Firefox.
