Per-site media autoplay controls: You can now control autoplay permissions on a per-site basis under the “Website permission” section of the Website Identification pane – just click the information icon or lock icon on the left side of the address bar and click “manage permissions” to get started.

Lookup definitions for words in Reading View, Books, and PDFs: We’ve added a new dictionary function, so you can look up definitions for key words when reading a page or document. Simply select a single word to see the definition appear above your selection.

You can choose to have a word read aloud to you to hear the correct pronunciation or expand more details from the definition. You can toggle whether definitions appear and which types of content they work in under the “General” tab of the Microsoft Edge settings menu.

Improved PDF toolbar: The PDF toolbar now shows text descriptions for icons, and adds options like “Add notes” to improve the discoverability of these tools. The toolbar can now be pinned to the top of the window when working with a document.

New design improvements: As we continue to evolve how Microsoft Edge leverages the Fluent Design System for a more natural and usable experience, you may notice some subtle tweaks to the look of the tab bar in Microsoft Edge. In this build, we’re adding a new depth effect to the tab bar to help emphasize the active tab.

Redesigned “…” menu and Settings: We’ve heard your feedback that the Microsoft Edge settings were getting a little complex for a single page. In this release, we’re overhauling the Microsoft Edge settings to make it easier to navigate, put commonly-used actions front and center, and allow more customization than ever. This build also breaks Settings out into subpages by category, with better-organized options and less clutter on each page. The new Settings experience is designed to match the experience in the Microsoft Edge hub, for a quicker and more familiar experience.

Customize toolbar items for Microsoft Edge: When you click “…” in the Microsoft Edge toolbar, you’ll find a refined menu that puts common commands like “New tab” and “New window” front and center. We’ve also added the much-requested ability to customize which icons appear in the Microsoft Edge toolbar – you can remove them all for a tidier look or add as many as you like to bring your favorite functionality to your fingertips!

Control whether media can play automatically: We’ve added a new setting in Microsoft Edge to allow you to control whether sites can autoplay media. You can find this setting under “Advanced Settings” > “Media autoplay,” with options to customize the behavior according to your preferences:

  • “Allow” is the default and will continue to play videos when a tab is first viewed in the foreground, at the site’s discretion.
  • “Limit“ will restrict autoplay to only work when videos are muted, so you‘re never surprised by sound. Once you click anywhere on the page, autoplay is re-enabled, and will continue to be allowed within that domain in that tab.
  • “Block” will prevent autoplay on all sites until you interact with the media content. Note that this may break some sites due to the strict enforcement – you may need to click multiple times for some video or audio to play correctly. Some sites may not work at all – in those cases, you can enable or block autoplay on a case-by-case bases from the website permissions pane (click the icon next to the address in the Address Bar).

Control whether media can play automatically: One common piece of Insider feedback for Microsoft Edge is that you want more control over autoplay videos. In this build, we’ve added a new setting in Microsoft Edge to allow you to control whether sites can autoplay media.

You can find an early preview of this setting under “Advanced Settings,” “Allow sites to automatically play media.” We’ll be improving these options and adding additional controls in upcoming flights and in response to your feedback, so stay tuned!

New, clearer “Settings and more” (“…”) menu: We’ve redesigned the “Settings and more” menu in Microsoft Edge so it’s easier to find the options you’re looking for. The menu options are now organized into groups, with icons for each entry, and keyboard shortcuts (where applicable). Click the “…” button in the top-right corner of Microsoft Edge to see what’s new

See your top sites in the Jump List: You can now see your top sites in the Jump List on the Windows taskbar or Start Menu. Just right-click the Microsoft Edge icon to see a list of your most visited sites and pin the ones that matter most to you. Right-click on any entry to remove it from the list.

Organize the tabs you’ve set aside: We’re making it easier to organize the groups of tabs you’ve set aside, so you can remember what’s in each group when come back to it later. Once you’ve set a group of tabs aside, choose the “Tabs you’ve set aside” icon (top left corner), and click on the label for any group to rename it.

Do more from the “Downloads” pane: We’ve added options for “Show in folder” and “Copy link” to the right-click menu for downloads in the “Downloads” pane.

Microsoft Edge tabs are now included in the alt-tab switching interface: Users can now toggle between tabs just like individual windows using the alt-tab menu in Windows. This can be configured in Windows Settings under System -> Multitasking -> Sets.

New web platform features

New in Windows 10 build 17692

WebDriver improvements: Beginning with this build, we’re making it easier than ever to automate testing in Microsoft Edge using WebDriver. First, we’ve made WebDriver a Windows Feature on Demand, so you no longer need to match the build/branch/flavor manually when installing WebDriver. When you take new Windows 10 updates, your WebDriver binary will be automatically updated to match.

To install WebDriver, just turn on Developer Mode in Windows 10 Settings, or install the standalone feature under the “optional features” Settings page.

We’ve also updated WebDriver to match the latest W3C Recommendation spec with major new improvements. You can learn all about these changes over at the Microsoft Edge Dev Blog.

New in Windows 10 build 17682

Web Authentication (WebAuthN) preview: Microsoft Edge now includes unprefixed support for the new Web Authentication API (a.k.a. WebAuthN). This evolves our previous support for the WebAuthN specification to enable the updated version of the API by default.
Web Authentication provides an open, scalable, and interoperable solution to facilitate authentication, which replaces passwords with stronger hardware-bound credentials.

The implementation in Microsoft Edge allows users to use Windows Hello (via PIN or biometrics) and external authenticators like FIDO2 Security Keys or FIDO U2F Security Keys, to securely authenticate to websites.

This is the stable release of EdgeHTML 17. To see everything that’s new in EdgeHTML, visit the Edge Dev Guide for EdgeHTML 17.

Deprecated

Retired XSS Filter: We are retiring the XSS filter in Microsoft Edge beginning in today’s build. Our customers remain protected thanks to modern standards like Content Security Policy, which provide more powerful, performant, and secure mechanisms to protect against content injection attacks, with high compatibility across modern browsers.
