How to Bypass the \"Do You Want to Close This Window\" Confirmation Prompt?

Suppress "Do You Want to Close This Window" Prompt in Browser Window Closure

The browser often prompts for confirmation when closing a window using the window.close(); function. To suppress this prompt, a technique can be employed:

To close a browser window without the confirmation prompt, follow this method:

1. Create an empty window with window.open('', '_self', '');.
2. Close the newly created window using window.close();.

This trick circumvents the confirmation prompt by replacing the current window with an empty one before closing it. As a result, no content that might prompt for confirmation remains in the browser.

Note that this method only works for windows that belong to the same origin as the parent window. If you attempt to close a window from a different origin, the browser will still display the confirmation prompt.
