Google's FLoC has a number of 'significant' privacy problems, Firefox says
Google’s new proposal for targeted ad tracking has a number of properties that could pose “significant” privacy risks to users, according to Firefox maker Mozilla.
On Thursday, Firefox published the results of an analysis of Google’s Federated Learning of Cohorts, or FLoC, proposal. Google believes the new “privacy-preserving” system could be used to replace third-party cookies for ad tracking purposes. Rescorla, however, says there are major privacy problems with the system.
