Get even closer to Facebook via Firefox
Screenshots
If you just can't get enough of Facebook, then Facebook Toolbar for Firefox is a free extension that gives you enhanced access to Facebook from Firefox. Facebook Toolbar sits quietly at the top of your browser and provides twelve essential shortcuts to different sections of Facebook, such as profile, friends, photos, and groups. It also features several icons to show you how many friend requests you have, messages you've received, and invitations to events and groups.
One of the handiest features of Facebook Toolbar is an alert system similar to an IM client that tells you if there has been any activity on your profile since you last logged on. However, if you have lots of friends, it can become a constant distraction while you are working. You can even have a sidebar of your friends' faces staring at you, although that may be taking it a bit too far.
Facebook Toolbar is a seriously addictive extension that could easily distract you from your work. But if you can't get enough Facebook in your life, then you'll love it.
