Blocking all 3rd party cookies tends to break quite a few things, as websites often use different domains to handle things like logins.

I’ve found addons like Cookie Autodelete to be a more functional option, it allows those cookies to exist until I close the tab, and if the domain isn’t on a whitelist, they get deleted five minutes later. And it works for first party cookies too.
It does take a while to build that whitelist, and sometimes you forget to set it and wipe something you’d rather have kept.
