The release of 1Blocker 6.0 introduced significant changes to the app's interface and underlying content-blocking mechanisms.

Some users have noticed that the tool previously known as Firewall appears to be missing from the app. In 1Blocker 6.0, we changed our approach to Firewall to align with the app's new look, so it's still there, protecting users' privacy against in-app trackers.

Firewall is now one of the filters of the Privacy section of 1Blocker. To access and manage its settings, navigate to Privacy > [Apps] > Block In-App Trackers.

It works the same way as before, blocking tracking requests other apps attempt to make and allowing users to see these attempts in the Recent Activity pane in real time.
