问题
I'd like to create a Chrome extension where, when a particular URL opens, another URL opens automatically in a new tab. Note that I'd like the new tab to open as soon as the first URL begins to load, not once it's finished loading.
So basically, you'd click on a link to the first URL, and two tabs would open; one containing the first URL, one containing the second URL.
However, I really don't know where to begin. I don't think it can be a content script because they can't access chrome.tabs. So I'm trying to use a background page but it's not working. Here's my bg.html:
<html>
<body>
<script type="text/javascript">
var o = new Object;
chrome.tabs.onCreated.addListener(
function(Tab tab)
{
chrome.tabs.create(o);
}
);
</script>
</body>
</html>
and my manifest:
{
"name": "My First Extension",
"version": "1.0",
"description": "The first extension that I made.",
"background_page": "bg.html",
"permissions": [
"tabs"
]
}

In a background page:
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
if(changeInfo.status == "loading" && tab.url == "http://old/url") {
chrome.tabs.create({url: "http://new/url"});
}
});
