Social-networking dependents, you know who you are and what you need. The Shareaholic Firefox add-on is primed to satisfy your cravings and compulsion with a few clicks. Essentially a hub for shortcut links to favorite social-networking sites like Facebook, Twitter, Digg, Delicious, Google Reader, FoxieWire, and Plurk, Shareaholic is a Firefox toolbar button that lets you mark or post Web sites and stories by selecting them from a drop-down menu. You can share the page you're on, or even right-click a link on a page to select the Shareaholic sharing options from the context menu.
Of course, Shareaholic lets you customize which of its supported services show up on that drop-down list. We especially liked being able to add notes to our Facebook shares, and to use Shareaholic as a quick way to e-mail links to friends. We had some trouble casting votes with Digg, but transferring links to the other services worked like a charm.
Shareaholic allows you share and send links directly from your browser. Submit the Web page you are currently viewing to digg, del.icio.us, facebook, Google bookmarks, magnolia, reddit, stumbleupon, and twitter. If you prefer, e-mail the Web page directly to a friend instead.
Also, Shareaholic has a real-time statistics from digg and del.icio.us. Check whether the Web page you're on has been dugg, and how many times it has been saved on del.icio.us. Stats displayed in your browser, at your request.
