Like other standard web browsers like Google Chrome, Mozilla Firefox and Apple Safari, Microsoft Edge also comes with the feature to show the Home button which helps you to quickly navigate to your favorite webpage, it may be any specific web URL which you wish to set as your custom homepage.
Go to Settings, then Advanced Settings. In Advanced Settings, turn on 'Show the Home Button' and set your homepage. After entering the URL of your homepage, click on 'Save'. Now, you'll see a home button before the address bar in Edge.
