Although Edge is now built on Google’s Chromium, a number of unique features do set it apart from Google’s Chrome browser. Since January of 2020, Microsoft’s Chromium-based Edge has replaced the previous versions of Edge. Even so, users were slow to adopt it and Microsoft eventually announced plans to relaunch Edge as a Chromium-based browser (Chromium is Google’s Open Source browser project). With Windows 10, Microsoft introduced its Edge browser to compete with Firefox and Chrome, making it the default browser pre-installed on millions of PCs sold.
