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.

The setting is not yet visible by default, but users may enable it in Chrome by making a change on the browser's experimental features page:

1. Load chrome://flags/#privacy-sandbox-settings-2 in the address bar of the web browser.
2. Set the flag to Enabled.
3. Restart Google Chrome.

The flag is available for in all versions of Chrome, and has the following description:

Enables the second set of privacy sandbox settings. Requires #privacy-sandbox-settings to also be enabled

When set to enabled, it unlocks the FLoC toggle that gives users control over the feature.

Note: Google is running experiments in select regions currently. Privacy sandbox trials and FLoC may be disabled in the browser depending on the region and automated participation in the experiment.

To manage FLoC, do the following:

1. Load chrome://settings/privacySandbox in the address bar of the browser.
2. If turned on, disable FLoC on the page to turn off FLoC.
3. You may also turn of Privacy Sandbox trials there, if turned on.

Closing Words

The only way to be really sure that FLoC does not come near your browsing is to use a browser that is not Google Chrome. Most of these offer better functionality than Google Chrome anyway at this point.
