How to get Windows username in a legacy (not WebExtensions) Firefox add-on?

I am working a Firefox add-on (which is written in JavaScript) and need to determine the Windows user currently logged on. Is there a way to do this?

Following code works for me instead of onload event with function calling:

var objUserInfo = new ActiveXObject("WScript.network");
document.write(objUserInfo.ComputerName+"<br>"); 
document.write(objUserInfo.UserDomain+"<br>"); 
document.write(objUserInfo.UserName+"<br>");  
var uname =  objUserInfo.UserName;
alert(uname);

Firefox already has Integrated Authentication built-in (many people don't know that).
See: https://developer.mozilla.org/en-US/docs/Integrated_Authentication

Here is a Popular Firefox addon that eases the configuration: https://addons.mozilla.org/nl/firefox/addon/integrated-auth-for-firefox/

Here is some extra explanation:

Good luck!

This does the trick on Windows:

function getUser() {
   return Components.classes["@mozilla.org/process/environment;1"].getService(Components.interfaces.nsIEnvironment).get('USERNAME');
}
