The List of Internal Page URLs in Microsoft Edge

The List of Internal Page URLs in Microsoft Edge Chromium

Microsoft Edge, similar to Google Chrome, Opera, and other chromium-based browsers, includes a list of internal web pages which can provide extra details about various browser features, allow changing them, and even simulating web page errors. 

Microsoft Edge is now a Chromium-based browser with a number of exclusive features like Read Aloud and services tied to Microsoft instead of Google.

The stable version of Microsoft Edge Chromium is available to the public for a while. The browser has already received a few updates, with support for ARM64 devices in Edge Stable 80. Also, Microsoft Edge is still supporting a number of aging Windows versions, including Windows 7, which has recently reached its end of support. Check out Windows Versions Supported by Microsoft Edge Chromium. Finally, interested users can download MSI installers for deployment and customization.

For pre-release versions, Microsoft is currently using three channels to deliver updates to Edge Insiders. The Canary channel receives updates daily (except Saturday and Sunday), the Dev channel is getting updates weekly, and the Beta channel is updated every 6 weeks. Microsoft is going to support Edge Chromium on Windows 7, 8.1 and 10, alongside macOS, Linux (coming in the future) and mobile apps on iOS and Android.

Internal Page URLs in Microsoft Edge Chromium

Most of the Chromium-based browsers have their own protocol for internal pages. In Chrome it is chrome://something, in Opera it is opera://something.  For Edge, Microsoft is using the edge protocol name that allows you to access its internal pages. For example, edge://sandbox shows the status of the sandbox feature in Microsoft Edge.

Here is the list of internal URLs which are available in Edge.
