Apple’s Private Relay blocks this type of cross site tracking.
Given this tracking is all server side, third party cookies across sites aren’t possible using this mechanism, and private relay cycles through your IP addresses frequently and uses common IPs across multiple users.
Regarding your other point, unless Google execs want to be thrown in jail / sued, they can’t use things like first party cookies for their benefit since that is against their terms of service.
Private Relay uses ingress and egress relays. The ingress proxy does know your IP but not which sites you are visiting and what you are doing. The egress proxy is only connected to the ingress, sees what you visit but does not know who you are. Both proxies are run by different parties.
With a VPN you would have to trust one provider, who sees all of your traffic.
Yeah that would be a useful service that Mozilla could offer and I'd actually pay for.
I don't like their VPN as it's too basic in terms of privacy protection and it's much more versatile to just sign up with Mullvad myself because then I can use it on other stuff than just the browser.
