You asked for it, and you got it!
The Shareaholic extension for Firefox makes it easy for you to submit the web page you’re viewing to digg, del.icio.us, facebook, google bookmarks, reddit and stumbleupon. If you prefer, you can also e-mail the web page to a friend!
It also tells you whether the web page you’re on has been dugg, and how many times it has been saved on del.icio.us.
Are you a shareaholic? I know I am 🙂 Get the extension here.
