Yeah, one of the ways I was sure the Facebook Container works is that although I pay for Youtube Premium and so ordinarily my Youtube doesn't have adverts etc inside the Facebook Container since it has no idea who I am, a Youtube video has adverts.

Facebook is so toxic now that I can't imagine allowing that to contaminate everything else. I saw today an advert which has been carefully designed to rage bait idiots, so that they can believe they're protesting government policy which doesn't exist, the makers get cheap attention for their product, Facebook gets revenue and the only loser is our society...

Facebook uses more advanced fingerprinting techniques than just cookies, even a few data points like IP address, User-Agent, and screen-size probably uniquely identify you and let them cross-correlate you between containers.

If you want actual anonymity you need to use something like the Tor Browser (which does lots of tricks to try to block fingerprinting as well as using a unique Tor circuit for every website you access).
