Mozilla Firefox 86 was released today with Total Cookie Protection, a new privacy feature that prevents web trackers from keeping tabs on your activity while browsing the web.
With the release of Firefox 86, all other Firefox development branches have also moved up a version bringing Firefox Beta to version 87, and the Nightly builds to version 88.
"Today, Firefox introduces Total Cookie Protection to Strict Mode. In Total Cookie Protection, every website gets its own 'cookie jar,' preventing cookies from being used to track you from site to site," the released notes read. "In addition, Total Cookie Protection makes a limited exception for cross-site cookies when they are needed for non-tracking purposes, such as those used by popular third-party login providers," Mozilla added.
Mozilla has been fighting ad tech companies' online tracking efforts since 2019 when it enabled enhanced tracking protection in Firefox by default to block cookies from known trackers automatically.
Starting with Firefox 85, the browser also comes with supercookie protection to block hidden trackers from keeping tabs on users' web browsing activity.
"In combination with the Supercookie Protections we announced last month, Total Cookie Protection provides comprehensive partitioning of cookies and other site data between websites in Firefox," Mozilla explained.
