What is the Difference Between Home Page vs. Startup Page vs. New Tab Page in Microsoft Edge
Like Google Chrome, Microsoft Edge treats the concept of a “home page” somewhat differently from classic browsers of the past (and from modern browsers such as Firefox and Safari). When you set a home page in Edge, it only serves as a page that is available when you click a home icon on the toolbar, which is hidden by default. There is not currently an option to use this same home page setting as the default page that appears when you open a new window or tab.
Somewhat confusingly, you can also set a “startup page” that appears when you first open the Edge app, but this is a different setting than the home page mentioned above. Finally, Edge also includes a “New Tab” page that displays whenever you open a new tab, which includes content you can customize, but you cannot disable it completely or assign a custom page to appear when you open a new tab.
