"Firefox 86 Introduces Total Cookie Protection"
> 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.
@schlink The name is misleading though: there is no such thing as total protection, since protection coverage depends on the user threat model.
Yet, as far as cookie tracking goes, this sounds like the most efficient solution which does not disables cookies or 3rd party cookies entirely. Which itself could be an issue: it recognizes legitimates 3rd party cookies in the first place.
