ARS Technica writes Mozilla is working on a social networking add-on for Firefox:
"When people think of tools for social interaction, e-mail and instant messenger are at the top of their list, not web browsers," wrote one of the Mozilla Labs team members on the Mozilla Labs Blog. The lab is working to change that with a new project called "The Coop," which will allow users to share interesting links with each other through a sort of browser buddy list.
The current mockup of The Coop involves a listing of friends down the side of the web browser, complete with avatars and a listing of each friend's "recently added Flickr photos, favourite YouTube videos, tagged web sites, composed blog posts, updated Facebook status," among other things. It would ultimately serve as an aggregator for all of the web-based information about that particular friend, pulling from multiple sources to show what that person is interested in on the web at any given time. Sharing content with a friend in the list involves dragging a link, photo, video, or something else to that person's avatar in the list, which the browser will then transmit to him or her. On the receiving end, the friend will see the sender's avatar "glowing," indicating that the sender had just sent something to check out.
