I'm trying to make Firefox add-on that could set data to specific text or password field in any web site how could I script this add on ??

ex: I want to log in my Gmail using this add-on where I'll store my account data on it. How I could pass my username and password from my add-on to Gmail website?

I've tried to run this code

 XULSchoolChrome.BrowserOverlay = {


sayHello : function(aEvent) {


let user= document.getElementById("username");
let pass= document.getElementById("passwd");

window.alert("the username is "+ user.getString);
  }
};

I'm running my add-on in yahoo log-in page ...

this the HTML from the site I've get the ID

I found the solution guys you have to use gbrowser as followed 

var currenttabIndex = gBrowser.tabContainer.getIndexOfItem(gBrowser.selectedTab);
var currentBrowser = gBrowser.getBrowserAtIndex(currenttabIndex);

var inputElementlist = currentBrowser.contentDocument.getElementsByTagName("input");
