Ask HN: Whats the difference between cross-site cookies and third-party cookies?

2 pointszagrebian2 comments

Firefox’s Enhanced Tracking Protection uses both the terms “cross-site cookies” and “third-party cookies”. What’s the difference?

I think Firefox comes with a pre-defined list of "Social media trackers", "Cryptominers", "Fingerprinters" domains so that's cross-site cookies. https://support.mozilla.org/en-US/kb/enhanced-tracking-prote...

It's confusing wording regardless. Doesn't help that on the help page https://support.mozilla.org/en-US/kb/firefox-options-prefere... they call it web cookies.

I think cryptominers are fingerprinters are scripts. Scripts are not cookies.
