Firefox only (Windows/Mac/Linux): Friendbar is a toolbar add-on for Firefox that can rapidly update your Facebook or Twitter statuses, and show a ticker-style stream of your friends' own text and photos. Friendbar continuously updates you on the status of people in your Facebook and Twitter networks, though both the text and the photos can be toggled on and off. To avoid running afoul of Twitter's access restrictions, Friendbar lets you dial down its update frequency, tweak how many messages it displays, and set how often it shows you new stuff. When posting updates, you've got instant TinyURL creation for the page you're looking at. If you can't pretend not to need a quick Facebook or Twitter fix while you're browsing other things, Friendbar makes it easy and fast to get your social data fix. Friendbar is free and works wherever Firefox does.
