Mozilla's Firefox Focus web browser can now protect Android users against cross-site tracking while browsing the Internet by preventing cookies from being used for advertising and monitoring your activity.
"We're bringing it to Firefox Focus on Android, our simple, privacy by default companion app. Firefox Focus on Android will be the first Firefox mobile browser to have Total Cookie Protection," Mozilla said today.
Two years ago, Mozilla enabled enhanced tracking protection in Firefox by default to automatically block cookies from known trackers.
With the launch of Firefox 72 in January 2020, the web browser also began auto-blocking scripts used for browser fingerprinting and added supercookie protection to stop hidden trackers from keeping tabs on users' web activity, starting with Firefox 85.
"In combining Total Cookie Protection with supercookie protections, you can ease your worries about companies tracking you from site to site by using Firefox Focus on Android," Mozilla added today.
Support for SmartBlock, a mechanism that makes sure Total Cookie Protection doesn't break websites when blocking tracking scripts, was also added to Firefox Focus for Android in December.
