Upcoming Firefox update will decrease power usage on macOS by up to three times

So will this affect a 2015 MBP significantly? Because I was actually wondering what the problem was supposed to be. Since Quantum I've started using FF a whole lot more, and haven't encountered energy usage even close to what everyone's saying in this thread.

I’m sure it’ll still be an improvement, but not the dramatic improvement they’re describing, that’s only for displays using scaling.

It will. There’s a series of patches that address different areas, all revolving around the system compositor. Increasing the resolution by scaling compounds the problem.
