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?
Solved in Nightly for me!
Not sure on the use of CoreAnimation.
For me, it isn't always in the "Using significant power" list.
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).
"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.
