Disabling Google's Federated Learning of Cohorts
Google's FLoC Is a Terrible Idea [eff.org], so I've disabled it on this site and all my other sites. I could say more, but the EFF put it better than I can.
Anyway, here's a snippet for Apache:
# disable Google's FLoC cohort tracking thing <IfModule mod_headers.c> Header always set Permissions-Policy: interest-cohort=() </IfModule>
My site is a drop in the ocean, but nevertheless, I won't have my site taking part in advertising data, the same way this site doesn't utilize third party cookies, or any advertising cookies at all.
Also, if you as a user are concerned about your privacy, consider Firefox, or maybe just about any other browser than Google Chrome.
