Microsoft Edge is a web browser developed by Microsoft. It was first released for Windows 10 and Xbox One in 2015, then for Android and iOS in 2017, and for macOS in 2019.
Edge includes integration with Cortana and has extensions hosted on the Microsoft Store. Unlike Internet Explorer, Edge does not support the legacy ActiveX and BHO technologies.
Originally built with Microsoft’s own EdgeHTML and Chakra engines, in 2019 Edge was rebuilt as a Chromium-based browser, using the Blink and V8 engines. As part of this change (codenamed Anaheim), Microsoft has made the preview builds of Chromium-based Edge available on Windows 7, 8, 8.1 and macOS, in addition to Windows 10. Microsoft released the first Chromium-based Edge version on January 15, 2020.
According to StatCounter, in August 2019 Edge overtook the market share of Internet Explorer (IE) on PC, Edge in fourth place and IE in fifth. While IE’s share dropped, no single version of Edge is more popular than Internet Explorer 11. The market share for Edge remains low, with IE following in this trend. However, combining the market share of Edge and IE, Microsoft’s browsers are third place in PC browser market share, Chrome being first and Firefox second. Mobile versions of Edge exist for Android and iOS, however they have little to no market share. On Microsoft consoles, Edge replaced IE as the dominant browser a few months after its release in 2015.
Market share varies by region. On some days of the week, Edge takes second place with a 10.02% share in the US on PC, and Firefox and Edge have very similar share globally, switch places for second and third rank depending on the day.

Stable channel security updates are listed here.
Initial Preferences in Microsoft Edge. Microsoft Edge now supports a limited number of Initial Preferences (formerly Master Preferences). IT admins can deploy these settings as default before the browser is run for the first time by their users. Additional information here: Configure Microsoft Edge using Initial Preferences settings for the first run.
IE mode on Microsoft Edge will support “no-merge” behavior. For an end-user, when a new browser window is launched from an IE mode application, it will be in a separate session, similar to the no-merge behavior in IE11. You will need to adjust your site list to configure sites that need to prevent session sharing as “no-merge”. Behind the scenes, for each window of Microsoft Edge, the first time an IE mode tab is visited within that window, if it is one of the designated “no-merge” sites, that window is locked into a different “no-merge” IE session from all other Microsoft Edge windows at least until the last IE mode tab is closed in that window. This follows previous behavior where users could launch IE with no-merge and could also launch Microsoft Edge without no-merge via other mechanisms.

New policy to stop implicit sign in. The ImplicitSignInEnabled policy allows system administrators to disable implicit sign-in on Microsoft Edge browsers.
Policies to bypass ClickOnce and DirectInvoke prompts. We have updated our policies to enable bypassing ClickOnce’s prompts and DirectInvoke’s app for specified file types, from specified domains. To do this, you will need to:
Enable ClickOnceEnabled or DirectInvokeEnabled
Enable AutoOpenFileTypes policy and set the list of specific file types that ClickOnce and DirectInvoke should be disabled for
Enable the AutoOpenAllowedForURLs policy and set the list of specific domains that ClickOnce and DirectInvoke will be disabled for.
Note: AutoOpenAllowedForURLs is a supporter policy for AutoOpenFileTypes. If AutoOpenAllowedForURLs is not set and AutoOpenFileTypes is set, then file types listed will automatically open from all URLs.
Tab Groups. We are turning on tab grouping which provides the ability to categorize tabs into user-defined groups and helps you more effectively find, switch and manage tabs across multiple workstreams.
Hide the title bar while using Vertical Tabs. Get the extra few pixels back by hiding the browser’s title bar, while in Vertical Tabs. Now you can go to edge://settings/appearance and under the Customize Toolbar section select the option to hide the title bar while in Vertical Tab mode.
Video Picture in Picture (PiP) from hover toolbar. When you hover over a supported video, a toolbar will appear that allows you to view that video in a PiP window. Please note: this is currently available for Microsoft Edge users on macOS.
Removal of 3DES in TLS. Support for the TLS_RSA_WITH_3DES_EDE_CBC_SHA cipher suite will be removed. This change is happening in the Chromium project, on which Microsoft Edge is based. For more information, navigate to the Chrome Platform Status entry. Additionally, in Microsoft Edge version 93, the TripleDESEnabled policy will be available to support scenarios that need to preserve compatibility with outdated servers. This compatibility policy will become obsolete and stop working in Microsoft Edge version 95. Ensure that you update affected servers before then.
