First-party isolation in Firefox: what breaks if you enable it?

Thanks for the clarification.

What surprises me the most is that not only Firefox but also my Safari Browser passes all those tests when ITP is enabled.

Safari by default has a stricter storage access policy by default for all third-party domains, which requires you to visit the domain as a first party first. So it's probably that rather than ITP.

I have a general question if you don't mind. I use Firefox Beta. Why is Firefox going the route of a manual blacklist (disconnect) instead of working on some kind of programmatic machine-learning/somewhat intelligent third-party storage blocking by default that doesn't discriminate known against unnkwon trackers?
