Here is how you disable FLoC in Google Chrome

The latest version of Google Chrome Canary has a new feature to disable FLoC -- Federated Learning of Cohorts -- in Google's Chrome web browser.

FLoC is part of Google's controversial plan to change the world of advertising. The core idea is to change the way users are tracked on the Internet. Instead of tracking individual users, FLoC introduces technology that allows advertisers to track users based on cohorts, groups of users who share the same interests.

FLoC is beneficial for Google, but not so much for Internet users. The EFF called FLoC a terrible idea, largely because it is not as private or better as Google advertised it.

Most Chromium-based browser makers reject FLoC outright. Brave and Vivaldi block FLoC in the browser already.

One option that Chrome users had to opt-out of Floc was to disable third-party cookies. Now, with Chrome Canary build 93.0.4528.0, comes a setting to control FLoC directly.
