Mozilla’s social sharing button has gotten a few new improvements. F1, from Mozilla Labs is proposed to be a future default feature in a later version of Firefox, so think we should learn as much about it as we can.
Mozilla is getting into the world of social link sharing. With F1, you can add the functionality of sharing a link on Twitter, Gmail or Facebook into the Firefox browser. This neat add-on has a lot of potential, and is simple enough for anybody to pick up and use.
