Please update your version of Firefox for the latest features and security updates.

Tracking generally refers to the collection of a person’s browsing data across multiple sites. The Tracking Protection feature uses a list provided by Disconnect to identify and block trackers.

You can read more about tracking and the standards Disconnect uses to create its list here. Learn more about the lists used by Firefox for Tracking Protection.

A shield icon will appear in your address bar whenever Firefox is blocking tracking domains.

To see which resources are being blocked, you can open the web console and look for messages under the Security tab.

How to turn Tracking Protection off

Tracking Protection is enabled by default when you're in a Private Browsing window. You may choose to disable Tracking Protection for a particular site or for all sites.

Turn off Tracking Protection for individual sites

  1. The shield icon will appear when Firefox is actively blocking trackers on a page. Click the shield icon to bring up the Control Center.
  2. In the Control Center, click Disable protection for this session.

  3. Once Tracking Protection is disabled, a shield icon with red strikethrough tracking protection off fxos will appear in your address bar.
To re-enable Tracking Protection, click the shield icon again and click Enable Protection.

Since Private Browsing mode doesn’t keep any information about your browsing session, when you disable Tracking Protection for a site, it only lasts for the session. When you start a new Private Browsing session, Tracking Protection will be turned on for all sites.

Turn off Tracking Protection for all sites

  1. Click the menu button new fx menu , followed by OptionsPreferences.
  2. Click Privacy, then uncheck the box next to Use Tracking Protection in Private Windows.
