Microsoft Edge 154.0 (155.0 Bêta, 156.0 Dev, 157.0 Canary)

Announcements

• Deprecating the unload event. Microsoft Edge is changing the default behavior of the web platform unload event. As the rollout progresses, pages will no longer run unload event handlers unless the site explicitly permits them.
  • In Edge 152 and 153, unload handlers will stop firing by default for 60% of page loads unless the site explicitly enables them through Permissions Policy.
  • In Edge 154, the rollout will increase to 80% of page loads.
  • In Edge 155, the rollout will reach 100% of page loads.
  The unload event is not a dependable way to save data, perform cleanup, or report the end of a session. Browsers and operating systems can suspend or terminate pages without firing it, and this can prevent pages from using the back/forward cache, which may make back and forward navigation slower.Web developers should migrate to lifecycle events and APIs designed for these scenarios. The long-term direction of the web platform is to remove support for unload.
• Retiring Windows Information Protection (WIP) and Microsoft Defender Application Guard (MDAG) in Microsoft Edge. The WIP and MDAG code paths are being retired from Microsoft Edge, aligning Edge with the Windows platform. Windows deprecated both technologies and removed them in Windows 11, version 24H2.Only tenants that configured WIP or MDAG in Microsoft Edge are impacted by this change. Both features are off by default and require an admin to turn them on, so tenants that never enabled them are not affected. In practice this is a small, Windows 10 population. Both features were committed for Windows 10 only, and both are already unavailable on Windows 11, version 24H2.For organizations using WIP, use Microsoft Purview Information Protection, Microsoft Purview endpoint DLP, and Data Loss Prevention and also Intune app protection policies for data protections instead of WIP.For organizations using MDAG, use the built-in Microsoft Edge for Business security capabilities and Microsoft Edge natively supports hardware isolation instead. Also further, Microsoft Defender SmartScreen, Enhanced Security Mode, Data Loss Prevention, and website typo protection is available.The change rolls out through the normal Microsoft Edge release channels, and will reach general availability with Microsoft Edge Stable 154 around September 24, 2026.

Feature Updates

• Improved profile setup in the first run experience. Microsoft Edge now includes a close (X) button in the upper-right corner of the new profile setup during the first run experience. When setup is canceled, Microsoft Edge automatically removes the incomplete profile to prevent unused profiles from being retained.
• Sign in to Edge with a Google account. Users can now sign in to Microsoft Edge using a Google account in addition to a Microsoft account from the profile menu and Edge sign-in screen. The feature is available on Windows and macOS devices. Admins can control availability using the NonMicrosoftAccountSignInEnabled policy.
• Enhanced Key Icon with Credential Details, Copy Actions, and Notes. The key icon in Microsoft Edge's address bar now lets users open a detailed panel for any saved credential. From there, users can copy a username, reveal and copy a password, and add personal notes to each login. Users can keep security questions, account purposes, or recovery details with credentials without opening Settings or the full password manager.
