<p>Interact with the browser's tab system. You can use this API to get a list of opened tabs and to create, modify, and rearrange tabs in the browser.</p>

<p>You can use most of this API without any special permission. However, to access <code>Tab.url</code>, <code>Tab.title</code>, and <code>Tab.faviconUrl</code>, you need to have the "tabs" <a href="https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/permissions">permission</a>. In Firefox this also means you need "tabs" to {{WebExtAPIRef("tabs.query", "query")}} by URL.</p>
