Firefox mozilla web extensions : How to know when a tab has finished loading, from the background page

I want to perform action after Page loaded through web extension in mozilla ,

I have tried same method available in chrome as bellow

browser.tabs.onUpdated.addListener(function (tabId , info) {
if (info.status === 'complete') {
// your code ...

But it is not working well I am not getting "complete" status in some of cases,sometimes multiple iframes are there in web page.

So is there any solution to check weather page loading completed?

You can use following way to solve your problem,

      browser.tabs.onUpdated.addListener(function(tabId, changeInfo,tab) {
       if (tab.status == "complete" && { 
      //Perform you task after page loaded    completely 

This is tested way by me in mozilla web extension Thanks
