I’ve only got superficial knowledge on this, but I believe Firefox does roughly that out of the box.
The feature that you’re asking for is called “first-party isolation”. It was implemented by the Tor Browser devs and upstreamed into Firefox, and it’s what the whole Container technology foots upon. You can activate it in Firefox by setting privacy.firstparty.isolate in about:config to true.
But as I understand, Firefox now ships dynamic first-party isolation (dFPI) out of the box. Which is FPI, with a few exceptions to ensure web compatibility.
This is part of a wider effort called State Partitioning. And they market it to users as Total Cookie Protection. It’s a bit confusing…
