Fixed various bugs and performance issues.

Feature updates

  • Enable organizational branding in Edge for Business. Enable your organization's branding assets from Entra onto profile-related UI for profiles signed in with an Entra ID (formerly known as Azure Active Directory) account. You can add your organization's details such as name to the profile pill, name and brand color to the profile flyout, and logo to overlay the Edge for Business taskbar icon. This branding can help users more easily differentiate between multiple profiles and browser windows.

    Default organizational branding can be enabled by admins through the following policies:

    Admins will need to have "company branding" assets configured in the Microsoft Entra admin center for branding assets to be applied to this feature.

    For more information, see Microsoft Edge for Business and Add company branding to your organization's sign-in page.

  • Microsoft Edge migrates the updates experience into Browser Essentials. Getting alerts on available Edge Updates will come from Browser Essentials instead of the Settings page for better visibility and experience. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

  • New Website Typo Protection policies. The built-in Website Typo Protection warns users if it appears there is a mistyped popular domain name which could land users on a malicious webpage. Administrators can control the availability and configure Website Typo Protection by using the PreventTyposquattingPromptOverride and TyposquattingAllowListDomains policies.

Feature updates

  • RendererAppContainer. For extra security benefits, the Windows native app container is enabled by default. Note: If Enterprise organizations identify a compatibility issue due to code injection from security software, they should follow up with the software publisher directly. Alternatively, they can use the RendererAppContainerEnabled policy to trade off the security benefits in Microsoft Edge with their other software.

  • Updated SmartActionsBlockList Policy. The SmartActionsBlockList policy is updated with new policy option mappings. Administrators can now configure the policy to control Smart actions like definitions on websites (smart_actions_website) or control Smart actions in pdfs and on websites (smart_actions).

  • Microsoft Edge Workspaces improvements for offline functionality. Any workspace opened on a device previously is cached locally and can be opened on that device from that cache even if it fails to connect. Changes persist on that device and are resolved into the synced version when a connection can finally be made. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

Feature updates

  • Behavioral changes to the beforeunload event. The behavior of the beforeunload event has changed. Calling preventDefault in a beforeunload event handler triggers a confirmation dialog. Setting returnValue to an empty string in a beforeunload event handler no longer triggers a confirmation dialog. This behavior takes effect starting in Microsoft Edge version 119. Administrators can temporarily opt out of this functionality by disabling the BeforeunloadEventCancelByPreventDefaultEnabled policy.

  • Split screen restore improvements. Split screen allows you to simultaneously work on multiple tasks across two, side-by-side screens in one browsing tab to boost your productivity and multitask more efficiently. Now after the browser is restarted and the previous session is restored, the split tab will also be restored.

  • Additional capability to manage sidebar apps. Administrators can utilize the "sidebar_auto_open_blocked" ExtensionSettings policy field to control the auto-open behavior of sidebar apps. For more information, see Detailed guide to the ExtensionSettings policy.

  • Updates to Microsoft Edge enterprise sync settings page. When the ForceSyncTypes and SyncTypesListDisabled polices are used concurrently, the sync settings page (edge://settings/profiles/sync) accurately show the status for each data type.
