      It is already a thing for 2 years, since this is just an update to an old blog post to say that they’ll do even more now.

      Aside from that, it wasn’t a thing, because as per the usual something on the web breaks when you change behavior like that, because some webpages rely on third-party cookies to provide their core functionality.

      Someone (in this case the Tor Browser devs) had to come up with a way to have third-party cookies and eat them, too but isolate them from the third-party cookies that got created on other webpages.
      On the technical side, this is called “first-party isolation”, and basically each domain you browse to gets its own cookie jar to store first- and third-party cookies in.

      Right? When I first started learning web dev (just a bit) I thought cookies were like that, quarantined to each website. Its insane that it hasnt been like that for this long

        Well, they were already quarantined to each website, but if that same website got embedded in half of all websites, that still enables a lot of tracking. So now they’re also quarantined to each website and the website it’s embedded in, if any.
