Firefox Nightly on macOS: decrease in power usage by a factor of about 3x

I tried it after the comments in a previous HN post (https://news.ycombinator.com/item?id=20850135).

My results were very positive when idle (I can finally start FF and have it in the background without fans blasting).

However, just scrolling up and down in the default mozilla website increases power usage brutally (macOs activity monitor showed the energy impact as 200).

I'm still glad to see that fixes are finally coming, even though it's not usable for me yet.

If we get to a point of having it fixed and being able to use webrenderer on macbooks to have the gpu drawing, it could be a 180 for firefox's usability on macOs

I would really like an ETA for the rest of the changes.

Odd, I've just tried with Current FF and I can't get usage scrolling up and down that page to get above 6.3%

I wonder if this discrepancy could have something to do with switching to discrete graphics or something along those lines. iMacs can run their graphics card always and are designed to take that noise into account. If OP has a laptop, he might be hearing the graphics card revving up after being idle.
