> This, according to a series of tests, has put Firefox on par with Chrome, in regards to power usage. So still not awesome, but a round of applause to the team nonetheless. Not a small achievement.

Whic is odd, as I find FF better than Chrome for energy usage, but still trailing Safari.

  The big X-factor is extensions. I think these stats usually measure the browsers where neither has any extensions installed.

    And I think Safari Extensions are pretty much non-existent now, so it's probably never going to be a fair comparison.

      They're mostly distributed on the App Store these days. The old distribution channels are still available, but installation using these trigger a warning.

  You didn't see the worst of the power usage issues manifest themselves until you ran the program on a Retina display using scaled windows.

    Yep, it's unusable for me at work on my scaled display. It isn't just power consumption, scrolling is noticeably slower. I've been checking in on this issue every release, looks like I'll finally be able to go back to Firefox after 70 is released.

      Until the big changes land, you can have Firefox opt out of window scaling. Get info on the Firefox app and then check ”Open in Low Resolution” on the get info panel, then restart the app. You can pick up more energy savings by telling Firefox to stop using transparency. Go to about:config, and set gfx.compositor.glcontext.opaque to true.

The good news is that this is just the initial CoreAnimation work. Further improvements are in store.
