Microsoft has adopted the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility. This new Microsoft Edge runs on the same Chromium web engine as the Google Chrome browser, offering you best in class web compatibility and performance.
The new Chromium based Microsoft Edge is supported on all versions of Windows 7, Windows 8.1, Windows 10, Windows Server (2016 and above), Windows Server (2008 R2 to 2012 R2), and macOS.
Starting with Microsoft Edge version 92, users will have the option to upgrade navigations from HTTP to HTTPS on domains likely to support this more secure protocol. This support can also be configured to attempt delivery over HTTPS for all domains. More secure connections help protect customers from man-in-the-middle attacks.
In Microsoft Edge Dev and Canary, you can enable the Automatic HTTPS experimental flag to enable support for Automatic HTTPS, which switches connections to websites from HTTP to HTTPS. If enabled, the Automatically switch to more secure connections with Automatic HTTPS setting can then be turned on/off or further configured in Settings > Privacy, search, and services.
