Firefox on Tuesday began rolling out Total Cookie Protection (TCP) by default to its Android app that automatically blocks cross-site tracking on consumers’ mobile devices.
TCP, first rolled out worldwide to Firefox on Windows, Mac, and Linux in February, confines cookies to the site where they were created without impacting the browsing experience, preventing companies from tracking from site to site.
With this latest Firefox update, Android users can now protect personal data as TCP automatically blocks cross-site tracking. They also can easily view last opened tabs and passwords across different devices when using their Firefox Account
The technology works by maintaining a separate “cookie jar” for each website visited. Any time a website, or third-party content embedded in a website, deposits a cookie in a browser, Firefox Android confines that cookie to the cookie jar assigned to that website. This way, no other websites can reach into the cookie jars that don’t belong to them and find out what the other websites’ cookies know about you.
Firefox’s privacy protection confines cookies to the site where they were created, preventing tracking companies from using the cookies to track browsing from site to site.
