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?

This does the trick on Windows:
function getUser() {
return Components.classes["@mozilla.org/process/environment;1"].getService(Components.interfaces.nsIEnvironment).get('USERNAME');
}

您可以使用nsIEnvironment接口来获取USERNAME环境变量。

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!
