Summary: Third-party cookies pose significant risks to user privacy, allowing trackers to monitor individuals across the web. Recognizing this, browser vendors have committed to phasing them out. To support this effort, we plan to prototype third-party cookie blocking in the Nightly channel. This will allow us to identify and address potential website compatibility issues as we move towards a broader rollout.
