Chrome and closing a specific tab URL - google-chrome-extension

Question

I need to close a specific tab in Google Chrome.
The behaviour is that an extension open up URL after she loaded and this can't be avoid.
This doesn't work :
#manifest.json
{
"name": "Close Tab Helpx Adobe",
"description": "Close the url http://www.example.com",
"version": "0.1",
"manifest_version": 2,
"app": {
"background": {
"scripts": ["background.js"],
"persistent": false
}
},
"icons": {
"16": "close-tab-helpx-adobe-16.png",
"128": "close-tab-helpx-adobe-128.png"
},
"permissions": [
"tabs"
]
}
#background.js
chrome.tabs.onUpdated.addListener(function(tab) {
if(tab.url=="http://www.example.com") {
chrome.tabs.remove(tab)
}
});
In developper mode, i can see Uncaught TypeError: Cannot read property 'onUpdated' of undefined
As you can see, i'm a beginner.
Do you know how to achieve this ?
EDIT:
I also tried :
#background.js
chrome.tabs.onActivated.addListener(function(activeInfo) {
chrome.tabs.get(activeInfo.tabId, function(tab){
if(tab.url=="http://www.example.com") {
chrome.tabs.remove(tab);
}
});
});
chrome.tabs.getCurrent(function(tab){
if(tab.url=="http://www.example.com") {
chrome.tabs.remove(tab);
}
});
chrome.tabs.query({currentWindow: true, active: true}, function(tabs){
if(tabs[0].url=="http://www.example.com") {
chrome.tabs.remove(tabs[0]);
}
});
The error is the same, only the property name change onActivated, getcurrent or query

Thanks to wOxxOm (and his patience), here is a code which do the job :
#manifest.json
{
"name": "Close Tab Helpx Adobe",
"description": "Close the url http://www.example.com",
"version": "0.1",
"manifest_version": 2,
"background": {
"scripts": ["background.js"],
"persistent": false
},
"icons": {
"16": "close-tab-helpx-adobe-16.png",
"128": "close-tab-helpx-adobe-128.png"
},
"permissions": [
"tabs"
]
}
#background.js
chrome.tabs.onCreated.addListener(function(tab) {
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
if(tab.url=="http://www.example.com") {
chrome.tabs.remove(tab.id);
}
});
});
So, i have my answer.
