<p>
You can use most <code>chrome.tabs</code> methods and events without declaring
any permissions in the extension's <a href="manifest">manifest</a> file.
However, if you require access to the
<code>$(ref:tabs.Tab.url url)</code>,
<code>$(ref:tabs.Tab.title title)</code>, or
<code>$(ref:tabs.Tab.favIconUrl favIconUrl)</code> properties of
<code>$(ref:tabs.Tab)</code>,
you must declare the <code>"tabs"</code> permission in the manifest,
as shown below:
</p>

<pre data-filename="manifest.json">
{
  "name": "My extension",
  ...
  <b>"permissions": [
    "tabs"
  ]</b>,
  ...
}
</pre>

You can find simple examples of manipulating tabs with the
<code>chrome.tabs</code> API in the
<a href="http://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extensions/docs/examples/api/tabs/">examples/api/tabs</a>
directory.
