I really want to change to Firefox but a while ago it was a huge battery drain on my mac. It had something to do with it not using CoreAnimation, I think. Does anyone know if this is still the case?

I think everyone sees different results based on their hardware and browsing habits. I haven't seen anything recent directly comparing Firefox/Chrome/Safari on Mac to Firefox/Chrome/Edge on PC using the same exact websites. For me, it isn't always in the "Using significant power" list.

Do you use a Retina display by chance? In certain setups, Fx is known to use more energy in HiDPI mode. Try disabling it and see if it fixes your issue. To what I know, this issue is known to Moz and will be fixed in a few versions (it appears to be a complex issue that takes time to solve).

  > In certain setups, Fx is known to use more energy in HiDPI mode. Try disabling it "Hey, your laptop is too good, please cripple it!" is not a good answer, especially considering retina displays have been out for 6 years now (and I bet loads of Moz employees use them too). I use Firefox almost exclusively, and still I wonder, sometimes, what the %$#%@ the "leadership" is thinking. They keep messing with crap like Pocket instead of concentrating on fundamentals like these.

    I was merely pointing out troubleshooting steps, not suggesting you take that as a solution to the issue. As I said, it‘s been worked on and latest nightly seems to improve that situation a bit.

  Pst, Moz and Mozilla are not the same thing.

I've been using FF on my 2015 MBP as my daily driver for at least 2 years and haven't had any problems. I mean, it's a battery hog for sure, but no more so than Chrome or any other modern browser with dozens of tabs open. Every once in a rare while flash will cause CPU usage to spike like crazy, but that isn't much of a problem anymore for obvious reasons. YMMV though I guess, it seems like a lot of people are still having performance issues, probably depending on which extensions are in use. Not sure on the use of CoreAnimation.

  What do you mean by daily driver?

    It usually means the main, default or preferred application.
