A new website lets Google Chrome users see if they have been auto-enrolled in an 'origin trial' of a new advertising technology which may eventually replace cookies. As we learn more about how the system will work, Google has already automatically switched on the new technology in the background of some Chrome users. For the 0.5 per cent of people enrolled into the origin trial without knowing, there are limited options to avoid being part of Google's experiment. Currently there are more than 33,000 different cohorts and a person's assigned FLoC ID, a number, is changed regularly. FLoC's origin trial being run by Google is only live on Chrome, so users of other browsers need not worry.
