Current Progress Report


Activity Stream for Firefox is a collection of all the things you do in the browser that you care about displayed in a rich and meaningful way. We plan to show rich content with images from recent pages, screen shots, downloads, closing sessions, notifications, and improve your results in the awesome bar. Eventually we hope to be the central feed of the things you care about.
