Window.Close() in MasterPage

Question

var exit = confirm("Do u want to close browser!");

if (exit) { window.close() }

else { }

 

If user clicks yes then i need to close browser but Window.close() is not working

its showing 

"Scripts may close only the windows that were opened by it."  

Its from Master page.

Is their any other way to close the browser with the help of javascript.
