Microsoft Edge (or simply Edge) is a proprietary, cross-platform web browser created by Microsoft. It was first released in 2015 as part of Windows 10 and Xbox One and later ported to other platforms as a fork of Google's Chromium open-source project: Android and iOS, macOS, older Windows versions (Windows 7, Windows Server 2008 R2 and later were supported until early 2023), and most recently Linux. Edge was created as the successor to Internet Explorer (IE).
Edge was initially built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. In late 2018, it was announced that Edge would be completely rebuilt as a Chromium-based browser with Blink and V8 engines. The new Edge was publicly released in January 2020, and on Xbox platforms in 2021. Microsoft has since terminated security support for the original browser (now referred to as Microsoft Edge Legacy), and in Windows 11 it is the default web browser (for compatibility with Google Chrome).
In May 2022, according to StatCounter, Microsoft Edge became the second most popular browser in the world, overtaking Apple's Safari (in some countries, such as the United States, Edge is the 3rd most popular, where it has a 14% share, slightly behind Safari's 16% share). , Edge is used by 11% of PCs worldwide.
Microsoft Edge is the default web browser on Windows 10, Windows 10 Mobile, Windows 11, Xbox One, and Xbox Series X and Series S consoles, replacing Internet Explorer 11 and Internet Explorer Mobile. As its development and release is dependent on the model of Windows as a service, it is not included in Windows 10 Enterprise Long-Term Servicing Channel (LTSC) builds.
Microsoft initially announced that Edge would support the legacy MSHTML (Trident) browser engine for backward compatibility, but later said that, due to "strong feedback," Edge would use a new engine, while Internet Explorer would continue to provide the legacy engine. The developer toolset of the EdgeHTML-based versions featured an option to emulate the rendering behaviour ("document mode") of Internet Explorer versions 5 to 11.
