With Focus privacy settings what is the difference between block cross-site cookies and block 3rd party cookies only? It isn't clear because Mozilla defines these as the same here https://support.mozilla.org/en-US/kb/third-party-cookies-firefox-tracking-protection. So what is the different setting? This seems to be a part of the Tracking protection which is Google's upstream code and linked to a criminal espionage bug of Google's. The code enabling this upstream criminal espionage bug is referenced by Mozilla as the Polaris project. Google was a little careful to not reject my reports of this criminal espionage bug as (intended) but plays incompetent and rejects the bug as (won't fix can't reproduce) although I have reproduced the bug in full documentation multiple times on multiple devices. My report is here https://github.com/users/freedom-foundation/projects/2
