Fixed various bugs and performance issues, feature updates, policy updates, and web platform release notes.

Stable channel security updates are listed here.

Announcement

• The Microsoft Edge Browser Policy Documentation has been updated to include mobile-specific policies. This update is intended to consolidate the desktop and mobile policies into a single location. There are no changes to the policies themselves; this is a documentation update only.

Feature updates

• Connected Feature Control (CFC). Admins now have centralized, granular control over cloud-powered and AI-driven services in Microsoft Edge such as Translate, Compose, and Auto Tab Grouping through ​Connected Feature Control (CFC). This new policy allows organizations to align Edge with their compliance and data protection standards by enabling or disabling specific connected experiences from a single location in the Edge Management Service portal. Note: This experience is starting public preview rollout and can be accessed by opting in to targeted release in the Microsoft 365 admin center.

• Recommendation for DiskCacheSize policy. It is recommended not to configure a custom value for the DiskCacheSize policy as Microsoft Edge automatically manages the cache size for optimal performance. Setting a small value can degrade performance and increase network usage.

• Scareware blocker. Scareware blocker in Microsoft Edge is your local AI powered shield designed to protect you and your users from scareware attacks. Feature availability and functionality may vary by device type, hardware configuration, region, and platform. Scareware blocker is enabled by default only on devices with more than 2GB of RAM and at least five processor cores. Devices that don't meet these minimum system requirements may require manual activation or may not support this feature. Admins can control availability to this feature using the ScarewareBlockerProtectionEnabled policy. For more information, see Scareware blocker.

• Tab Groups – Auto-Save and Easy Revisit. Microsoft Edge now automatically saves tab groups, making it easier than ever for users to pick up where they left off. Organized tab groups are preserved and ready to revisit anytime, whether a user is switching tasks or restarting the browser. Admins can control the availability of the feature using the SyncTypesListDisabled policy with the “openTabs” data type.

• HTTPS-first mode. HTTPS-first mode in Microsoft Edge automatically upgrades HTTP connections to HTTPS when possible. If a site doesn’t support HTTPS, Microsoft Edge shows a warning to highlight the security risk. This appears only for public sites—not private ones or manually entered HTTP URLs. Users can enable the warning in edge://settings and admins can control availability to this feature using the HttpsOnlyMode policy. For more information, see Secure your web browsing with HTTPS-First Mode in Microsoft Edge.

• Third-party storage partitioning policy updates. The ThirdPartyStoragePartitioningBlockedForOrigins and DefaultThirdPartyStoragePartitioningSetting policies are deprecated in Microsoft Edge version 140 and they're planned to be obsoleted in Microsoft Edge version 145. Replacement for these policies is usage of the requestStorageAccess method. For more information, see Document: requestStorageAccess() method - Web APIs.

• Enhancement to Edge updates. Microsoft is introducing an improvement to the Settings and more menu (“…” on the menu bar) which makes it easier for users to discover when a browser update is available.

• Improved Navigation to Extension Surfaces. To improve visibility and discoverability, Microsoft Edge is introducing two navigation improvements for extensions. First, if a user has at least one enabled extension, the puzzle icon is persistent on the toolbar. Second, from the Settings and more menu, the Extensions option allows users to reach edge://extensions and the Edge Add-ons Store directly. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Updated Collected Cookies dialog to improve performance. The Collected Cookies dialog is rewritten to improve page responsiveness. Customer-facing functionality and UX from previous releases remain the same.

• Reset Microsoft Edge enterprise sync. For users having problems syncing browsing data across other signed-in devices, they can reset sync data from the Microsoft servers via Edge Settings edge://settings/profiles/sync/reset. This option should only be used if the sync data is available on one of the user's devices or if they want to delete all sync data from the servers. Note: In Microsoft Edge 139, reset sync is enabled for users encountering a "No permissions" MIP error and in Microsoft Edge 140, reset sync is enabled for users encountering a "Service disabled" MIP error.

• Update to Microsoft AutoUpdate policy. The MAUEnabled policy allowed admins to continue using Microsoft AutoUpdate on macOS. Since Microsoft Edge now uses EdgeUpdate, the MAUEnabled policy is obsoleted in Microsoft Edge version 140.

• Create AI generated videos with Bing. Bing Video Creator empowers users to generate AI-driven videos using text prompts, using Sora technology to bring ideas to life with ease and creativity. Available exclusively to personal Microsoft Account holders, it offers both free and fast creation modes—enhanced by Microsoft Rewards points—for producing high-quality, short-form videos directly within Bing. For more information, see Bing Video Creator | Microsoft Bing.

• Boost productivity and learning. With AI-driven recognition, Bing Visual Search, Edge users can get access to contextual insights and actionable information without leaving the browsing flow. You can access Visual Search by right clicking on images and selecting "Visual Search" from the drop-down menu.

• Auto-discarding Sleeping Tabs. Tabs that have been sleeping for a long time will be discarded to save memory. When a user navigates back to a discarded tab, the tab needs to be reloaded. This can be managed through the AutoDiscardSleepingTabsEnabled policy. This policy is enabled if the SleepingTabsEnabled policy is enabled.

• Reduce IP Address Change Notification policy updates. The ReduceIPAddressChangeNotificationEnabled policy allows admins to control the reduced IP address change notification behavior in Microsoft Edge on macOS. For issues related to connectivity with VPN connections and proxy server usage, disabling this policy setting may help to address them.

• Changes to Wallet in Microsoft Edge. Wallet is being phased out to support a streamlined experience within Microsoft Edge. This affects the Wallet feature in Settings and the Mini Wallet found by clicking the profile icon in the top banner. For more information, see Changes to Wallet in Microsoft Edge.

Fixes

• Fixed an issue where MIP-protected PDF files from different sovereign cloud environments (including GCCH) failed to open and instead displayed the error message: “Need permissions. Contact the owner of the file to give you permissions.”

• Fixed an issue, which affected IE mode, including errors when displaying PDF files, running Java applets, and showing the Information Bar in IE mode.

Improved reliability

• Fixed a browser crash that occurred on first launch when the BrowserSignin policy was enabled and configured to "Force (2) = Force users to sign-in to use the browser (all profiles)."

Feature updates

• Open external links in another profile when recommended by external applications. When Microsoft Edge is set as the default browser to open external links from applications, Microsoft Edge must determine which profile to open the links. Users can control which profile to use through the “Default profile for external links” setting. Applications such as Microsoft Teams or Outlook can also recommend a profile for the links. Currently, the user setting is prioritized over application recommendations. With this feature, the application recommended profile is given priority, instead of the profile selected in the setting. Admins can control the availability of the feature using the EdgeOpenExternalLinksWithAppSpecifiedProfile policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Changes to Wallet in Microsoft Edge. Wallet is being phased out to support a streamlined experience within Microsoft Edge. This affects the Wallet feature in Settings and the Mini Wallet found by clicking the profile icon in the top banner. Users are directed to the new Passwords, Payment, and Personal Information management experience in Settings. Also, a new Password management experience is available in Settings. For more information, see Changes to Wallet in Microsoft Edge. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Introducing a new policy that can enable/disable Microsoft 365 Copilot Chat in Edge for Business from showing in the toolbar. Edge for Business now has a dedicated policy, Microsoft365CopilotChatIconEnabled, to enable and disable Copilot in Edge from showing in the Edge toolbar. When both this policy and HubsSidebarEnabled are configured, this policy takes precedence in determining whether Copilot appears in the toolbar. If this policy isn't configured and HubsSidebarEnabled is disabled, Copilot will remain hidden. In a future release, this policy is the sole control for managing Copilot's visibility in the toolbar.

• Real-time notifications for compromised passwords. Microsoft Edge is integrating an in-context password breach notification system. This feature proactively informs users if their saved login credentials have been compromised in known data breaches, enabling them to take immediate action to secure their accounts. Admins can control availability to this feature using the PasswordMonitorAllowed policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Edge Settings Improvements. Edge Settings is migrating to WebUI2 to boost page responsiveness and introducing a series of minor visual and content upgrades to improve overall usability and utility. This includes optimizing for concise wording of individual settings, simplifying the number of pages and reorganizing content, and creating a cohesive user interface.

• New Autofill Personal Information Settings Configuration. A web form field collection consent toggle will be available in Autofill settings (edge://settings/autofill/personalInfo). This allows users to consent to Microsoft Edge collecting web form field labels (e.g., "First Name," "Email") to improve Autofill suggestion accuracy. Only field labels are collected and not user-entered data. The web field labels are stored securely per Microsoft's privacy standards.

  This new setting is manageable via existing policies in Autofill (e.g., AutofillAddressEnabled), EdgeAutofillMlEnabled. AutofillAddressEnabledis the parent setting forEdgeAutofillMlEnabled. The EdgeAutofillMlEnabled policy is the parent of this new setting, thus turning off the EdgeAutofillMlEnabled policy turns off this setting.

• Web AI APIs for prompt and writing assistance. Microsoft Edge now implements the Writing Assistance APIs and the Prompt API (for Edge extensions) with a local language model, Phi-4-mini, that is built into the browser. These easy-to-use JavaScript APIs are made available via Edge flags (set to Enabled, by default only for the Summarizer and Prompt API for extensions) so that sites and extensions can apply AI capabilities on the web. The small language model is downloaded as the first time any of these APIs is used and later shared across all domains, serving local AI use-cases with reduced cost, network independence, and increased privacy (since data input to the model doesn't leave the user’s device). Admins can control the availability of these APIs via the GenAILocalFoundationalModelSettings policy. These APIs are currently not implemented in China. Read the announcement here, and feel free to provide feedback.

• Enhancements to Performance and Secure network. Browser essentials is now separated into two distinct experiences (Performance and Secure Network) - both available from the Settings and more menu (“…” on the menu bar).

• Reset Microsoft Edge enterprise sync. For users having problems syncing browsing data across other signed-in devices, they can reset sync data from the Microsoft servers via Edge Settings edge://settings/profiles/sync/reset. This option should only be used if the sync data is available on one of the user's devices or if they want to delete all sync data from the servers. Note: In Microsoft Edge 139, reset sync is enabled for users encountering a "No permissions" MIP error and in Microsoft Edge 140, reset sync is enabled for users encountering a "Service disabled" MIP error.

• Update to Microsoft AutoUpdate policy. The MAUEnabled policy allowed admins to continue using Microsoft AutoUpdate on macOS. Since Microsoft Edge now uses EdgeUpdate, the MAUEnabled policy is planned to be obsoleted in Microsoft Edge version 140.
