Mozilla Announces Total Cookie Protection Feature for Firefox 86

Mozilla has announced a new Total Cookie Protection privacy feature for Firefox 86 built into ETP Strict Mode. Total Cookie Protection confines cookies to the site where they were created, which prevents tracking companies from using these cookies to track your browsing from site to site.

-----
Our new feature, Total Cookie Protection, works by maintaining a separate “cookie jar” for each website you visit. Any time a website, or third-party content embedded in a website, deposits a cookie in your browser, that cookie is confined to the cookie jar assigned to that website, such that it is not allowed to be shared with any other website.

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. Only when Total Cookie Protection detects that you intend to use a provider, will it give that provider permission to use a cross-site cookie specifically for the site you’re currently visiting. Such momentary exceptions allow for strong privacy protection without affecting your browsing experience.

Mozilla says that in combination with the Supercookie Protections announced last month, Total Cookie Protection provides comprehensive partitioning of cookies and other site data between websites in Firefox. Together, the features prevent websites from being able to 'tag' your browser and eliminate the cross-site tracking technique.
