Overview:<br>
<br>
Activity Stream is a Firefox about:newtab and about:home replacement that aims to help users return quickly and easily to contextually relevant stuff on the web.  It is currently implemented as an Add-on SDK/Jetpack add-on, and has been running as a TestPilot experiment for some months.<br>
<br>
Activity Stream is implemented in JS, and uses the React (<a href="https://facebook.github.io/react/" rel="noreferrer" target="_blank">https://facebook.github.io/<wbr>react/</a>) UI library.  The add-on reports UI telemetry pings back to Mozilla servers using ping-centre (<a href="https://github.com/mozilla/ping-centre" rel="noreferrer" target="_blank">https://github.com/mozilla/<wbr>ping-centre</a>).  There is a brief overview of it’s architecture on our Github page (<a href="https://github.com/mozilla/activity-stream/wiki" rel="noreferrer" target="_blank">https://github.com/mozilla/<wbr>activity-stream/wiki</a>).<br>
<br>
Activity Stream has been developed using a series of A/B test based experiments, both on an opt-in Test Pilot and an opt-out production Shield audience.  Our methodology is to continue optimizing the user experience along the user engagement and user retention dimensions.  The about:newtab and about:home pages that land in Firefox will be measurably more engaging than the existing experience.<br>
<br>
<br>
Timeline:<br>
<br>
We are currently in the process of landing the Activity Stream MVP to replace about:newtab and about:home in mozilla-central.  Our target milestone is to land a fully functional MVP for Firefox 56 (by April 17, 2017)<br>
