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. - MozillaIn an effort to not affect your browsing experience, there are some exceptions to the rule. For example, Mozilla says it's still allowing cross-site cookies for certain non-tracking purposes. The foundation explains this is necessary to support popular third-party login providers. Full details can be read at the Mozilla blog.
