The Mozilla foundation has just released an new addon for Firefox: the Coop addon.
This addon will let user keep track of what their friends are doing online and share content with one or more of those friends.
Users will see their friends’faces, and will be able to get the list of the recent actions (latest photos added to Flicker, favourite YouTube videos, tagged websites, composed blog posts…)
Users can share content be dragging that content onto their friends’face. When they receive something from a friend, that friend’s face glows to get the user’s attention.
