Version 139.0.3405.86: August 7, 2025

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

Stable channel security updates are listed here.

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.

Feature updates

• Edge contextual capabilities in Business Chat work tab. Microsoft Copilot in Edge now supports page summarization and contextual queries to the Work tab for Microsoft 365 Copilot Business Chat. With this feature, users can ask Copilot contextual queries such as “summarize this page.” This feature also includes contextual prompt suggestions to help users ask relevant questions about open pages in Edge. Page summarization and contextual prompt suggestions is accessible for users when using Copilot through the Edge side pane.

  A Microsoft 365 Copilot license is required to use this feature. Administrators can control the availability using the EdgeEntraCopilotPageContext policy.

Version 138.0.3351.95: July 16, 2025

Fixed various bugs, feature updates, and performance issues for Stable Channel.

Stable channel security updates are listed here.

Feature updates

• Microsoft Edge policies to manage Shadow IT. This feature restricts access to non-Microsoft Generative AI tools using Edge policies. Using the WebContentFilteringBlockedCategories policy, admins can restrict access to other LLMs (except Copilot Chat) along with all browsers (except Microsoft Edge). This helps admins address the shadow IT problem, which is the use of Gen AI tools without oversight of IT admins in the organization. Some of these Gen AI apps can cause data loss and don't comply with the organization's security policies.

Version 138.0.3351.83: July 10, 2025

Fixed various bugs and performance issues for Stable Channel.

Improved reliability

• Fixed a browser crash that occurred when the BrowsingDataLifetime policy was enabled.

Version 138.0.3351.77: July 7, 2025

Fixed various bugs and performance issues and feature updates.

Fixes

• Reverted a change that caused audio issues when playing videos with AAC audio on certain websites. This is planned to be a temporary mitigation, as the root cause is a bug in outdated versions of the HLS.js library used by websites. Affected site owners are encouraged to update to a newer version of HLS.js to ensure compatibility.

Feature Updates

• Find on Page in Microsoft Edge for Business will soon be integrated with Microsoft 365 Copilot Chat. Microsoft Edge for Business is introducing Microsoft 365 Copilot Chat to Find on Page (CTRL+F). This feature seeks to help users more easily find relevant content and save time.

Stable channel security updates are listed here.

Fixes

• Fixed an issue, which caused WebDriver automation to fail in Microsoft Edge versions 133 and later.

• Fixed an issue where re-enabled <textarea> elements remained noneditable. This issue affected activating a role assignment in Privileged Identity Management.

Feature updates

• Inline protections integrated with Microsoft Purview. Microsoft Edge for Business is introducing integrated protections using Microsoft Purview. Without using browser extensions, Admins in Purview can configure policies to collect and protect data that users share with unmanaged generative AI apps, detecting for sensitive information inline and auditing or blocking the interaction accordingly.

• Use Primary work profile as default profile to open external links. Microsoft Edge currently opens external links using the “Last Used” profile by default. While for enterprise users, the Primary Work Profile (signed in with a Microsoft Entra ID for enrolling the device) is normally the best profile for opening external links. With this feature, for Windows, Edge checks if the Primary Work Profile exists and makes it the default profile for opening external links if available. For Mac and Linux, if only one work profile signed in with a Microsoft Entra ID account is found, it’s treated as the Primary Work Profile. Admins can control availability to this feature using the EdgeOpenExternalLinksWithPrimaryWorkProfileEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• New Autofill Personal Information Settings Configuration. A web form field collection consent toggle is available in Autofill settings (edge://settings/autofill/personalInfo). This allows users to consent to Microsoft Edge collecting web form field labels (for example, "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 (for example, AutofillAddressEnabled, EdgeAutofillMlEnabled. AutofillAddressEnabled) is the parent setting for (EdgeAutofillMlEnabled)[/deployedge/microsoft-edge-browser-policies/edgeautofillmlenabled]. The EdgeAutofillMlEnabled policy is the parent of this new setting, thus turning off the EdgeAutofillMlEnabled policy turns off this setting. Note: These features are a controlled feature rollout. If you don't see these features, check back as we continue our rollout.

• AI-powered History search. Enhanced search finds sites in your History even when you use a synonym, phrase, or typo. After this feature is turned on, sites you visit will be shown in enhanced history search results. An on-device model is trained using your data, which never leaves your device and is never sent to Microsoft. Admins can control availability to this feature using the EdgeHistoryAISearchEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Microsoft 365 Copilot Chat Summarization in Microsoft Edge Context Menu. Microsoft Edge is introducing a Microsoft 365 Copilot Chat summarization menu item to our context menu. This feature helps users quickly unpack and ask questions about their open page. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Improvements to surfacing performance notifications. Microsoft Edge is making improvements to how users can learn about and improve their browser's responsiveness. Performance and Extensions Detector notifications may appear in the Settings and more menu when Edge's performance slows. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Copilot on the Microsoft Edge New Tab Page (NTP). Starting at the end of May 2025, users may see suggested work and productivity-related Copilot prompts by their search box on the NTP page. Also, users may see the Copilot icon in their search box allowing them to click on the icon to send their current search query to Copilot. The Copilot admin policy NewTabPageBingChatEnabled continues to be enforced and will still apply. NTP changes are rolled out to all Microsoft Edge release channels. Note: These features are a controlled feature rollout. If you don't see these features, check back as we continue our rollout.

• Adding support for viewing Sensitivity labels applied to a Microsoft Information Protection (MIP) Protected PDF. Enterprise customers can view sensitivity labels applied to MIP protected PDF to be well informed of the data classification to enable them to handle such sensitive documents. This change is available in the new Microsoft Edge built-in PDF reader. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
