Internet Explorer mode on Microsoft Edge Chromium

Alongside all the features and improvements in the roadmap for the new version of Microsoft Edge based on the Chromium engine, Microsoft is including a compatibility mode using the Internet Explorer rendering engine to load old websites.

The feature is known as “IE Mode,” and it’s designed for organizations to load internal sites without the need to use a separate browser or having to redesign the site. The new approach loads the pages within Microsoft Edge just like a normal website without the need to use and manage multiple browsers.
