IE mode on Edge

IE mode on Edge

Internet Explorer 11 will be retired and out of support in June, 2022. So why do you need IE mode on Edge? The answer is Microsoft’s long tail of compatibility for business customers.

Google kills ‘flagship’ products more ruthlessly than Hannibal Lector. Apple drops products and persuades customers they were old hat and it’s time to spend some money on new Apple stuff.

Microsoft, however, lives in terror of bad publicity from every insurance company, healthcare provider, local government department and law firm whenever there’s a hint that a third party product might stop working with Windows. This is why Win-32 is firmly embedded in Windows 10.

Internet Explorer is finally going away. But Redmond has included an IE compatibility mode in the Chromium-based Edge browser. It’s the equivalent of bolting a buggy whip onto a Tesla.

According to Microsoft itself: “IE mode on Microsoft Edge makes it easy to use all of the sites your organization needs in a single browser.”

In a recent post, MS declared:

“We created Internet Explorer (IE) mode in Microsoft Edge for organizations that still need Internet Explorer 11 for backward compatibility with existing websites but also need a modern browser. This feature makes it easier for organizations to use one browser, for legacy web/apps or for a modern web/app.”

Or, put another way, it stops customers screaming like petulant children if they think they need to spend money to replace fifteen year-old intranets and websites.

What is IE mode?

Microsoft Edge version 77 or later uses the integrated Chromium engine for modern sites, and the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites.

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

IE mode supports for Internet Explorer functionality includes:

  • All document modes and enterprise modes
  • ActiveX controls (such as Java or Silverlight)
  • Browser Helper Objects
  • Internet Explorer settings and Group Policies that affect the security zone settings and Protected Mode
  • The F12 developer tools for IE, when launch with IEChooser
  • Microsoft Edge extensions (Extensions that interact with the IE page content directly are not supported)

IE mode doesn’t support:

  • Internet Explorer toolbars
  • Internet Explorer settings and Group Policies that affect the navigation menu (for example – search engines, and home pages.)
  • IE11 or Microsoft Edge F12 developer tools

You can’t miss the irony in Microsoft’s statement:

“With Microsoft Edge, we provide a path to the web’s future while still respecting the web’s past.”

Expect Microsoft to start writing the greetings for Hallmark cards soon.

However, you should also note:

“This retirement does not affect in-market Windows 10 LTSC or Server Internet Explorer 11 desktop applications. It also does not affect the MSHTML (Trident) engine.”
