The inspector/network tab it looks the same as it did with Chrome. Can we have items loaded marked as 3rd, 4th, 5th party etc. Not only that, but which other item loaded them. And that info be added to a HAR file made so that we can draw directed graphs elsewhere like Ghostery did - https://www.google.com/search?q=ghostery+trackermap&source=lnms&tbm=isch
Note too, I mage an open source demo to give a visual effect of 3rd, 4th, 5th (etc) - https://github.com/paul-hammant/ad-infinitum/ - animated gif in README.
