So - is this a NEW browser? He mentions that he won&#x27;t run this on firefox.<p>Is &quot;Servo&quot; their &quot;next&quot; browser?  What does the mozilla ecosystem look like?  Will this technology get folded in to firefox?<p>This is really cool but there&#x27;s a tonne of stuff here that I&#x27;ve never heard of.<p>Can anyone explain it like I&#x27;m five?  How does this fit into the big picture?
