Microsoft has disabled Google's controversial FLoC browser-based tracking feature in their Chromium-based Microsoft Edge browser.
This month, Google began testing a new tracking platform called Federated Learning of Cohorts, or FLoC, that places users in anonymous buckets, or cohorts, based on their interest and browsing behavior.
As FLoC is a Google browser-based feature, it is currently only supported on Google Chrome and Chromium-based browsers through a component named 'Federated Learning of Cohorts.
When building Chromium-based browsers, Google has enabled support for FLoC by default, as shown in Chromium's source code.
Such is the case with Microsoft Edge, where FLoC has not been enabled, and the component is not available in the browser even if enabled via command-line arguments.
Even with the lack of support from browser developers and privacy advocates, with Google holding close to a 70% web browser market share, it may be challenging to get rid of FLoC at this point for those who use Google Chrome.
