Reduce battery usage?
Firefox consistently uses 75% of my battery life, even with few tabs and on non-intensive sites. Is there any way to decrease its battery usage, e.g. a power-saving mode?

Re: Reduce battery usage?
Why do you think this is a Firefox issue? Do you visit the same set of sites using other browsers and find that there is less battery consumption?

Re: Reduce battery usage?
I do notice Firefox using more power than MS Edge when watching YouTube videos. On my laptop when watching the same video Edge uses less than 9-10, while Firefox uses 12-13w. Another thing I notice is that ClockRes(from system internals) reports timer resolution set to <1ms when using Firefox, and Edge on 15.6ms when looking at the same (empty) page.

Re: Reduce battery usage?
Is that meaningful?
1 vs 15.6?
(Man I had to download the newer version just to see as mine was from 2004! .)
Now, that was with both browsers closed (SeaMonkey & FF), but with whatever else I have open (much), & I'm still at 1.
(And I not about to close Everything down to see.)
But is it meaningful?

Charge.
Open FF to about:blank.
Time.
Wait to die.
Charge.
Open Chrome to about:blank.
Time.
Wait to die.
Then do similar with a page that loads content.
Oh, maybe pick some really long video on YT, say, https://www.youtube.com/watch?v=zq7rSaPit30, which covers 18 hours (if run at 1/2 speed), which is probably longer then your battery will last.
Run that in FF.
Run that in Chrome.
Wait for that beep at the end of 18 hours.
Did your battery last longer running Chrome then it did running FF?
(You could even set up a cam to watch all of this & post it on YT .)
And it would seem that mozilla is aware of such things.

And you would assume, regardless of what ClockRes may show - at a particular instant, that they are actually on par with Chrome.
