For those of you still need to support IE
After more than 25 years, Microsoft is finally retiring Internet Explorer. The aging web browser has largely been unused by most consumers for years, but Microsoft is putting the final nail in the Internet Explorer coffin on June 15th, 2022, by retiring it in favor of Microsoft Edge.

Good news is Microsoft Edge come with IE Compatible mode. From Settings → Default browser, you will find the Internet Explorer mode setting, which would load your page under IE engine.
However, Debugging IE webpage under Edge needs a little trick
Trying to debug IE mode web page from Edge browser? After press F12, you would see “DevTools disconnected”. This is due to Edge browser Developer Tools binding with Chromium engine.
Fortunately, Windows OS come with IE compatible mode, hence IE DevTools. IEChooser came to rescue.

- Open IEChooser.

Enter%systemroot%\system32\f12\IEChooser.exe, and then select Ok. - In IEChooser, select the entry for the IE mode tab.
Once you pick the web page opened with IE mode, you will see your familiar IE Developer Tools.
