Enhanced Tracking Protection in Firefox automatically protects your privacy while you browse. It blocks trackers that follow you around online to collect information about your browsing habits and interests without breaking site functionality. It also includes protections against harmful scripts, such as malware that drains your battery.
To see what’s been blocked on all sites over the past week, visit your Protections Dashboard. Click the shield in the address bar
and select Protections Dashboard or type about:protections into the address bar. This will open the Protections Dashboard page in a new tab.
What Enhanced Tracking Protection blocks
Firefox uses a list of known trackers provided by Disconnect. By default, Firefox blocks the following types of trackers and scripts.
Social media trackers
Cross-site tracking cookies (also isolates remaining cookies)
Tracking content: These trackers are hidden in ads, videos, and other in-page content. In Standard mode, tracking content is blocked in Private Windows. To add this protection in all windows, visit your privacy preferences and select Strict or Custom as explained below.
The shield to the left of the address bar tells if you if Firefox is blocking trackers and scripts on a site.
Active: Firefox blocked trackers and harmful scripts on a site. Open the shield to see what was blocked.
Crossed out: Enhanced Tracking Protection is turned off on a site. Open the shield and toggle the switch to turn it back on.
How to tell what’s being blocked on a site
Click on the shield to see what Firefox has blocked.
This panel will display different information depending on the site you’re on.

Firefox only allows trackers and scripts needed for the site to work and blocks the rest. For more information, visit SmartBlock for Enhanced Tracking Protection.
None Detected: Firefox looked for these trackers and scripts, but did not find them on this site.

to the left of the address bar.

You may encounter breakage on some sites when you’re in Strict Enhanced Tracking Protection. This is because trackers are hidden in some content. For example, a website might embed an outside video or social media post that contains trackers. To block the trackers, Firefox must also block the content itself. Trackers are often hidden in the following types of content:
