Exactly the same with me: I've been trying to use Firefox over the past month on a MBP, but Chrome is definitely faster (both UI-wise and seemingly with connections/requests - maybe Chrome is pre-empting some things?), and for me Firefox demonstrably uses more CPU across multiple cores, so laptop temp is noticeably hotter for the same sites, and fans spin a lot more, and battery life is worse.
