For those who don't care to read the full article:

This basically just confines any cookies generated on a page, to just that page.

So, instead of a cookie from, say, Facebook, being stored on site A, then requested for tracking purposes on site B, each individual site would be sent its own separate Facebook cookie, that only gets used on that site, preventing it from tracking you anywhere outside of the specific site you got it from in the first place.

Hahahahaha so it doesn't break anything that still relies on cookies, but neuters the ability to share them.

That's awesome

Honestly, I thought that's how it already worked.

Edit: I think what I'm remembering is that you can define the cookies by site/domain, and restrict to just those. And normally would, for security reasons.

But some asshole sites like Facebook are cookies that are world-readable for tracking, and this breaks that.

Someone correct me if I got it wrong.

Total Cookie Protection was already a feature, (introduced on Feb 23st 2021) but it was only for people using Firefox's Enhanced Tracking Protection (ETP) on strict mode.

They had a less powerful third-party cookie blocking feature for users that didn't have ETP on strict mode, that blocked third party cookies on specific block lists. (i.e. known tracking companies)

This just expanded that original functionality, by making it happen on any domain, and have it be the default for all users, rather than an opt-in feature of Enhanced Tracking Protection.
