My one issue with Firefox right now is CPU use. On my iMac or on desktop it doesn't truly matter. But on a MBP no matter how many tabs I have or what I'm doing the fans never turn on with Chrome. On Firefox they turn on regularly.
I've tested while looking at the activity monitor a bit. Loading random sites like HN show Firefox spiking to 80-90% CPU while Chrome spikes to 20-30%.

I have the same issue on my Linux laptop. It seems like Firefox always maxes out at least one core when loading pages or rendering pages with certain video codecs. I'm guessing Chrome throttles its performance or maybe it's just more performant.

On my 2012 MBA opening HN spikes very briefly to 25%. As others have pointed out, if you're genuinely hitting performance bugs then record a profile and fill a bug report.
