Users of Internet Explorer must be familiar with the Compatibility View that it offers. The Compatibility View allows users to view sites, that may be using older technologies, correctly - as some websites that were designed for earlier versions of Internet Explorer might not display correctly in IE9 and later. Thus Internet Explorer offered Compatibility View setting.
Compatibility View setting in Microsoft Edge browser
Microsoft Edge has been designed to use the latest web technologies. So if a site that you are trying to view uses older technologies, like some Frames or ActiveX controls, it will not render properly in Edge.
So what can a user do in such cases? Is there a Compatibility View setting in Microsoft Edge browser.
Nope!
If you are browsing a website that older technologies and you face problems in either opening the websites or making it render properly when using Edge, what you will have to do is click on the 3-dotted More button in the top right corner and select Open with Internet Explorer.
Internet Explorer will launch and open that site.
Hope this helps!
