Facebook has released an official browser toolbar
, and somewhat surprisingly it's available for Firefox only. It displays the number of pokes, friend requests, and messages you have waiting for you and has the obligatory search box and Share button for sharing links
, videos, etc. It also has notifications for when your friends change their statuses, write notes, or interact with you in other ways.
Finally, the add-on lets you open a sidebar that displays all of your friends for quick messaging, poking, and wall posts. The free add-on will be a welcome tool for the truly Facebook-addicted. It's a wonder MySpace didn't think of it first.
