Display a notification (count) in the browser (tab) favicon
Updates the favicon displayed in the browser (usually in the tab) to display a 'bubble' notification (number).
Can be used (for instance) to draw the users attention to messages/alerts received in a tab that is not currently active.
Note that you have to set up a working favicon for the extension to work.
Also note that the library currently degrades to title update for Internet Explorer 9 and Safari 5, while Chrome, Firefox and Opera is fully supported.
The add-on is Apache 2 licensed, the tinycon.js library that's used has a MIT license.
