Firefox browser apart from blocking trackers, it to populate and show the number of trackers it blocked so far and in a week by type at “about:protections” page from the profile creation date by using content blocking database. The page at the moment is showing a graph with dummy data, soon protections report will display real numbers for users in Firefox 69.
Current Firefox stable that ships with “Standard” content blocking mode for new users, has Enhanced Tracking Protection (ETP) enabled by default and by using Disconnect list, it blocks known third-party tracking cookies automatically.
In Nightly, Mozilla is making Enhanced tracking protection more powerful, it has now moved Cryptominers and Fingerprinters to Standard setting and will provide more data visually by showing a graph at about:protections to let the users know how many trackers it blocked over the last week by day-wise and the user protection level set to, whether it is standard or strict or custom.
Protection graph report classifies the trackers into different types (check their names below) and provides easy to understand descriptions for them.
For instance, for Social Tracker, it says “social media like, post and comments on the websites can track you -even if you don’t use them. Logging into sites using your Facebook or Twitter account is another way they can track what you do on those sites. We remove these trackers so Facebook and Twitter see less of what you do online”
Here are the other blocked tackers info Firefox displays on protections report page.
- Cross-site tracker: Cross-site tracking cookies
- Ad Tracker: Tracking Content
- Fingerprinter: Fingerprinters
Here is how Mozilla is planning the user to discover about: protections page. It will add a new “Trackers blocked this week” footer section with “show full report” link pointing to about: protections pages to protections panel (you can see this by clicking on Site identity icon). When the user clicks on the link in footer abou t:protections page will open and display the blocked trackers information.
UPDATE July 13, 2019: The Protection report now also shows information about Firefox lockwise password manager if you’ve enabled and using. For instance, it shows the number of passwords the service stored securely and synced to other devices.
