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.

The initial blocklist used by Tracking Protection is based on Disconnect's blocklist.

How to turn on Tracking Protection

  1. In the Location bar, type about:config and press EnterReturn.

    • The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page.
  2. Search for privacy.trackingprotection.enabled.
  3. Double-click privacy.trackingprotection.enabled to toggle its value to true.

This will turn on Tracking Protection. If you later want to turn it back off, repeat the above steps to toggle the preference back to false.

How to use Tracking Protection

Once Tracking Protection is activated, you will see a shield in your address bar whenever Firefox is blocking either tracking domains or mixed content.
