Need an update utility that will allow you to update your status for multiple networks at once? FireStatus does a good job at that. It is a nice looking Firefox add-on that lets you update Facebook, Twitter, FriendFeed, Delicious and Identi.ca all at once. That can save you a lot of time.
Here is a little more about the add-on from the developers:
FireStatus is a Firefox extension that allows you to send status updates, notes and URL links simultaneously to multiple social networks and services, like Twitter, FaceBook and FriendFeed. It also displays updates from these services in notification popups, for a more “live” communication with your friends.
