When i’m looking in a Chrome extension plugin there is a class or something like that called Chrome.extension

For example:

chrome.extension.onRequest.addListener(function(request, sender, response) {
  if (request.msg == 'page_capturable') {
    $('tip').style.display = 'none';
    $('capture........
    ........................
    ........................

The URL for the example

As you see there are several functions inside this chrome.extension like onRequest,getBackgroundPage() and others…

I checked with Firefox browser and it support this chrome.extension too…

I want to try and add this class to my html files, to enabled this functions with JavaScript or something a like

I’m going to try and use it inside Internet explorer.

Is there someone that can light me on this topic?
maybe a URL or the package it self?

BTW: I took google chrome extension and manage to convert it to Firefox
This is my proof that Firefox support this chrome.extension thing
Chrome on Firefox
