"Everything is chrome in the future."

The article doesn't really say anything new, but _why_ are most browser forks of Chrome instead of Firefox? Is chrome just that much easier to fork? I remember there used to be Camino for mac that was killed and rolled into firefox, and even to this day firefox support on mac is poor. The lack of a firefox equivalent to Electron also hurts things, even though it seemed firefox was ahead of the curve with XUL.
