How to disable popup "The webpage you are viewing is trying to close the tab"?

Question

I am trying to open a web application in MS Edge in IE compatibility mode. Everytime I launch the application, a popup comes saying "The webpage you are viewing is trying to close the tab. Do you want to close this tab?"

Application works fine after clicking "Yes".

The popup is not generated if I launch the same application on Internet Explorer.

 

Is there a setting in Edge to disable this popup?

Hi @Arsalan afzal,

After I tested it, as you said, the popup is not generated if I launch the same application on Internet Explorer.

In IE mode, you can add the window.open() method and reference the "_self" attribute to disable this pop-up in the window you want to close.

Here is part of the code I debugged:

<script>

window.onload = function() {
window.open('', '_self');
  window.close();
}
</script>
