A big problem of early Quantum Firefox on HiDPI Macs was its high battery usage. I think it got slightly better with later releases, but I don't have data to support that.

For people running in non-default scaled resolutions. In the default configuration it's somewhere in between Safari (best) and Chrome (worst).

  Unfortunately, a non-native scaling mode is the default on new Mac laptops now. You need to switch to one of the custom scaling modes to get a true, native 2x.

    I've heard this but haven't seen it on any new hardware — I thought it was limited to 2016 or so.

  I have never run my MacBook Pro in anything but the default scaling resolution. Quantum has been and continues to be a nightmare on my device. Unusably slow performance with high CPU utilization and occasionally spiking CPU utilization to 100% for prolonged periods. Usually long enough that I am forced to reboot the laptop.
