Google has started testing the phasing out of third-party cookies on Chrome, affecting about 1% of its users or approximately 30 million people.

Based on the test results and whether it causes significant issues with the displaying of websites, Google will begin to gradually phase out third-party cookies for the rest of its users starting in the third quarter of 2024.

Google Chrome users who are added to the third-party cookie deprecation tests will not be notified.

Google has shared information in a support document on how to check if you are part of the test.

For users not included in the 1% or those who haven't manually blocked third-party cookies via Chrome settings, Chrome DevTools will display warnings about potential cross-site cookie issues.

If you are not part of the test but want to join it manually, you can enable tracking protection by going to chrome://flags in the address bar and turning on an experimental flag titled "Test Third Party Cookie Phaseout." When prompted, relaunch the browser for the setting to go into effect.
