What Is Tracking Protection?
Tracking Protection allows you to take control of your privacy online. While Firefox has a Do Not Track feature that tells websites not to monitor your behavior, companies are not required to honor it. Firefox's Tracking Protection feature puts the control back in your hands by actively blocking domains and sites that are known to track users.
