Internet Explorer mode in Microsoft Edge

What is IE mode?

Internet Explorer mode on Microsoft Edge uses the integrated Chromium engine for modern sites, and it uses the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites. So if you have a page that has yet to be upgraded to format or function with a newer browser such as Edge, Chrome, Firefox, etc, this will be a way that you can use the pages necessary while Microsoft continues to phase out Internet Explorer.

When a site loads in IE mode, the IE logo indicator displays on the left side of navigation bar. You can click the IE logo indicator to display additional information, as shown:

IE mode supports the following Internet Explorer functionality

All document modes and enterprise modes
ActiveX controls (such as Java or Silverlight). Note: Silverlight reaches end of support on October 12, 2021.
Browser Helper Objects
Internet Explorer settings and group policies that affect security zone settings and Protected Mode
F12 developer tools for IE, when launched with IEChooser
Microsoft Edge extensions (Extensions that interact with the IE page content directly are not supported.)

Internet Explorer toolbars
Internet Explorer settings and group policies that control the navigation menu.

Congratulations, you have now enabled IE mode for Microsoft Edge!
