Firefox 86 Introduces Total Cookie Protection:
Today we are pleased to announce Total Cookie Protection, a major privacy advance in Firefox 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.
[...] In 2019, Firefox introduced Enhanced Tracking Protection by default, blocking cookies from companies that have been identified as trackers by our partners at Disconnect. But we wanted to take protections to the next level and create even more comprehensive protections against cookie-based tracking to ensure that no cookies can be used to track you from site to site as you browse the web.
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.
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. Together these features prevent websites from being able to "tag" your browser, thereby eliminating the most pervasive cross-site tracking technique.
