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.
