Twitterbar is a Firefox/Flock extension used to submit tweets straight from your browser. All you have to do, is type in your tweet into the address bar and press the big button to send it. Hovering over the button shows how many characters you have left.
This makes it easy to tweet exactly what site you’re on. If you use Firefox or Flock on a daily basis, this is the extension for you.
