Does this mean Microsoft Edge is deprecating third-party cookies?
The path for the future of the web is clear: third-party cookies are headed for removal. At the same time, we believe it's important to measure the impact of such a change and ensure we help make the shift at a responsible time. It's critical that the industry tests the Ad Selection API and provides feedback early to ensure that we have a clear understanding of the ecosystem's readiness. Microsoft Edge will start experimenting with deprecating third-party cookies in the coming months, targeting less than 1% of non-managed device users, and continue throughout 2024. This will enable us to measure and evaluate the various impacts to customers and partners, and encourage the ecosystem to proactively prepare for the eventual removal. Commercial customers using Microsoft Edge on managed devices will not be impacted by these experiments. We will share additional details regarding managed devices at a later date. However, we strongly encourage commercial customers to begin testing their public and internal sites, as described below, to ensure they and their partner ISVs have time to update their sites. We will share a timeline for a broader rollout at a future date and will continually measure ecosystem readiness throughout the process.Proactively testing
For parties interested in the Ad Selection API, more details will be shared as implementation progresses. We invite testing and adoption of the Ad Selection API by the industry in the second half of 2024. This timeline is subject to change as we learn more about how the changes impact customers and partners and get feedback from the industry. In the future, Microsoft Edge will generally block third-party cookies by default. Note that the changes planned for third-party cookie deprecation function differently than what happens when turning off third-party cookies via the Edge Settings (edge://settings/content/cookies
) which currently turns off all third-party storage entirely. Instead, after the change, the browser will still allow explicitly partitioned cookies and automatically partition other storage. Partitioned storage is not shared across web sites. For all web developers, we recommend testing your site with this change to how third-party cookies function. Proactive testing will enable you to identify user experience impacts within your site and update on a timeline that you are more in control of. You can test third-party cookie deprecation in Microsoft Edge today:
- Go to
edge://flags/#test-third-party-cookie-phaseout
in a new tab. - Enable the Test Third Party Cookie Phaseout flag.
- Restart Microsoft Edge.
