This API is experimental. It is only available to Chrome users on the dev channel.

chrome.infobars

Description: Use the chrome.infobars API to add a horizontal panel just above a tab's contents. See the screenshot below.
Availability: Dev channel only.
Permissions: "infobars"

The infobars API allows you to add a horizontal panel just above a tab's contents, as the following screenshot shows.

An infobar asking whether the user wants to translate the current page

Use an infobar to tell the reader something about a particular page. When the user leaves the page for which the infobar is displayed, Google Chrome automatically closes the infobar.

You implement the content of your infobar using HTML. Because infobars are ordinary pages inside an extension, they can communicate with other extension pages.

Manifest

The infobars API is avaiable under "infobars" permission and dev channel only. Also, you should specify a 16x16-pixel icon for display next to your infobar. For example:

      {
        "name": "Andy's infobar extension",
        "version": "1.0",
        "permissions": ["infobars"],
        "icons": {
          "16": "16.png"
        },
        "background": {
          "scripts": ["background.js"]
        }
      }
