Customize your "new tab" extension

**dhanushka** · 10-27-2009, 08:07 AM

I'm writing an extension. in the mainfest.json i used the following code.

{
"format_version": 1,
"version": "1.0",
"name": "myextension",
"background_page": "background.html",
"content_scripts": [
{
"matches": ["chrome://newtab/*"],
"js": ["abc.js"]
}
]
}

which gave the " could not load the extension .......
invalid value for 'content_script[0]. matches[0]'. " error message

I'm using google chrome 4.0.213.1 div version. In which there is a inbuilt newtab

content scripts are no longer supported on chrome:// pages.

Here's what I used today and it works, giving access to the Tabs API (though I don't like that way it works);

{
"name": "NewTab",
"version": "1.0",
"description": "Opens new tab pages blank, or with your own HTML page.",
"background_page": "background.html",
"matches": ["http://*/*", "https://*/*", "file://*"],
"permissions": ["tabs", "http://*/*"],
"run_at": "document_start"
}

and you can check for newtab in code;

<html>
<head>
<script>
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo) {
chrome.tabs.get(tabId, function(tab) {
if (tab.url.indexOf("chrome://newtab") != -1)
chrome.tabs.update(tab.id, {url: "about:blank"});
});
});
</script>
</head>
</html>

How about an easy solution to turning off the "most visited" tabs for tech dummies without having to change to the Dev version that is too complicated?
