What this extension does when you click it:

Shows if the current site is using FLoC
Shows if the current site is explicitly blocking FLoC data collection
More info: W3C is creating a new tracking system, first implemented in Chrome, called the Federated Learning of Cohorts (FLoC). This new tracking API categorizes people based on their browsing history and gives a cohort ID to a website that requests it. A cohort could contain a range of people, some could be in the thousands.

This could replace third party cookies, which will soon be removed in Chrome.
