Announcements​


  • New PDF Viewer Enabled by Default in Microsoft Edge. In Microsoft Edge Stable version 141, the Adobe-powered PDF viewer is now the default experience for enterprise users on Windows. Migration will occur on a phased rollout and will continue over the next few months. This change enhances performance, accessibility, and compatibility, and introduces exclusive enterprise features. Admins can manage the experience using the NewPDFReaderEnabled policy which controls the default viewer in Edge for Windows or the NewPDFReaderWebView2List policy which controls viewer behavior in WebView2 apps. For more information, see the FAQ page. Also, tenant admins can find additional details in the Message Center section of the Microsoft 365 Admin Center under MC1154300.
  • Local Network Access. Local Network Access in Microsoft Edge is a security feature that restricts a website’s ability to send requests to servers on your local network. When a website tries to connect, Microsoft Edge shows a prompt asking you to grant or deny permission. This protects privacy and security while maintaining compatibility with modern web standards. The ability of a website to request this permission from users is restricted to secure contexts. This feature is currently disabled by default in Microsoft Edge, but the default state will change starting in Edge 143. Enterprise administrators can configure Local Network Access policies. More information for users and administrators can be found here: Control a website’s access to the local network in Microsoft Edge.

Fixes​


  • Fixed an issue where a UIA (UI Automation) element recursively referenced itself as a child, causing timeouts and memory issues.

Feature Updates​


  • Real-time video translation. Real-time video translation. If you're learning a new language, or just like to watch foreign videos with subtitles in your preferred language, Microsoft Edge can help. With real-time video translation in Edge, you can watch videos in a different language with translated audio dub. Feature availability and functionality may vary by device type, hardware configuration (minimum 12 GB RAM and 4-core CPU), region, and platform. Availability is limited to select markets. For more information, see Real-time video translation | Microsoft Edge. Admins can control availability to this feature using the LiveVideoTranslationEnabled policy.
  • Policy to 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. This policy is the sole control for managing Copilot's visibility in the toolbar and the HubsSidebarEnabledd policy will no longer control the visibility of the Copilot toolbar button.
  • Tab preview on hover policy. The ShowTabPreviewEnabled policy lets administrators control whether Microsoft Edge displays a preview of the tab content when the user hovers over a tab. If the policy is enabled or not configured, Microsoft Edge shows a tab preview when the user hovers over a tab.
  • Update to "Clear Browsing Data on Close" behavior. The "Clear browsing data on close" setting (edge://settings/privacy/clearBrowsingData/clearOnClose) no longer supports automatic deletion of Passwords and Autofill data. The Passwords and Autofill form data toggles have been removed from the Settings page. Manual deletion of Passwords and Autofill remains possible via the "Delete browsing data" settings. The other data types (Browsing history, Download history, Cookies, Cached images, and Site permissions) are unaffected and can still be cleared on exit. This update does not impact enterprise policies, which continue to function as expected.

Version 142.0.3595.53: October 31, 2025​


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


Stable channel security updates are listed here.


Announcements​


  • Important update regarding the rollout of the Auto-Open feature. We’ve identified an issue with the initial implementation of the Auto-Open feature—it didn’t fully respect user preferences, and some settings weren’t honored as intended.
    To address this, the changes are being rolled back in phases during the next month to ensure all user preferences are correctly honored. As a result, users may temporarily notice a return to previous behavior where the sidepane opens even if the sidebar visibility is set to Off.
    Here are a few ways to manage the auto-open experience:
    • Manually Turn Off Auto-Open Pane: Users can manually disable the Auto-Open experience by navigating to the settings page if they prefer not to see the sidepane open for Outlook and Teams links.
    • Automatic Engagement-Based Logic: If a user doesn't engage with the Auto-Open experience and quickly closes it three times in a row, the feature is automatically turned off.
    • Turn off Auto-Open Pane using admin policies: Admins can control the Auto-Open experience by using either of these policies.
      1. HubsSidebarEnabled: Set as "False" to turn off
      2. ExtensionSettings: Set the sidebar_auto_open_blocked flag as "True" to turn off

Fixes​


  • Fixed an issue in headless mode which caused features like Print to PDF and Screenshot to not work as expected.

Feature updates​


  • Configuration update for MIP Enforcement. Starting in Microsoft Edge 142, new configuration step introduced to maintain MIP protections via Microsoft Edge management service. Existing settings remain active until admins choose to update. For more information, see Protect Office documents with Microsoft Purview Information Protection labeling.
  • SmartScreen and Scareware blocker. In organizations where both Scareware blocker and SmartScreen are enabled, users will now have the option to send signals to SmartScreen. The new setting “Share detected scam sites with Microsoft Defender SmartScreen” is available under edge://settings/privacy/security. If enabled, Scareware blocker will report its verdict to Microsoft Defender SmartScreen to enhance protection. Admins can control availability to this feature using the ScarewareBlockerSendDetectedSitesToSmartScreenEnabled policy.
  • New Scareware blocker policies. Introducing two new policies for admins to configure Scareware blocker. The first, ScarewareBlockerAllowListDomains, configures a list of trusted domains for Microsoft Edge Scareware blocker. When a website's source URL matches any domain in this list, Microsoft Edge Scareware blocker doesn't analyze that site. The second, ScarewareBlockerBlocksDetectedSitesEnabled, blocks sites that are detected as potential tech scams. For both of these new policies, they will only take effect if the ScarewareBlockerProtectionEnabled policy is enabled.
  • Drag to group tabs. Tab groupings can be made by dragging a tab over another. This feature can now be controlled by the "Drag to group tabs" toggle in Microsoft Edge Settings edge://settings/appearance/tabs.
  • 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.
  • Improved Autofill experience in Microsoft Edge. When users fill in an Address on a form, they will be prompted to choose whether to save it for future Autofill suggestions. This enhancement ensures Autofill data is saved intentionally by users and reduces unwanted entries as part of their Autofill suggestion. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
