It doesn't matter if Firefox has caught up if their usage share is still dropping. With Microsoft moving to a Chromium based browser as well, Firefox is very close to being irrelevant. More than 90% of the market will be Webkit or Blink. In my opinion, despite their technical achievements, Firefox is currently headed down the same path Opera went down before they became essentially a Chromium reskin. Their dropping usage share is negatively affecting sites compatibility with Firefox, which is the only reason I went back to Chrome after giving Quantum a try.
