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. Total Cookie Protection is designed to force all sites to keep their cookies in separate “jars” to block attempts to track you across the web and build browsing profiles. The move is part of Mozilla’s long string of changes to the Firefox browser while fighting ad tech companies’ online tracking effort.
