chrome.tabs.onUpdated.addListener is getting complete status twice or more for each page

Question

Here is my Script, which uses onUpdated.addListener to check each url:

chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {          
 alert(cha         


        

Answer 1

This was a known bug in Chrome Issue 162543 which was marked as fixed on 2012-12-05.

Workaround: (not needed anymore)

Make Event Page to Background Page by changing code from

"background": {
    "scripts": ["js/eventPage.js"],
    "persistent": false
  },

to

"background": {
    "scripts": ["js/eventPage.js"],
    "persistent": true
  },

and moving ahead by using background pages for development till the fix is delivered.

Other Points:

After a look at your manifest.json why does

"background": {
    "scripts": ["js/eventPage.js"],
    "persistent": false
  },
  "content_scripts": [
    {
      "matches": ["http://*/*"],
      "js": ["js/eventPage.js"]
    }
  ],

js/eventPage.js is made content script as well as background\event script; Having code for chrome.tabs.onUpdated.addListener() will not work in content scripts at all, please eliminate this code

Let me know if you need more information.
