Firefox’s exploration of bringing social networking features into the browser has moved forward a step. There is now a very rough prototype of “Coop” available as a Firefox Add-on that tries out some of the ideas discussed on the Firefox Labs wiki.

The Add-on can be downloaded here. Only early adopters who want to see what Firefox is up to will be interested in trying this out - for now it simply pulls some basic Facebook functionality into the browser.

But it does show what the product might eventually look like. The Add-on prompts you to log into Facebook. It then pulls all of your facebook friends into the sidebar. You can share any link, photo or video with a friend by simply dragging it into their picture.
