I know it's just anecdata, but on my 2 year old phone, Firefox+Adblock+NoScript uses about 33% less power than the stock Chrome. I grant that my browsing habits aren't such that I tend to use a lot of media-heavy sites in the first place, so perhaps on those I wouldn't see such savings.

I do the same, and honestly it's why I still use Firefox on mobile at all. But stock Firefox (which is what most people use anyways) has clear issues.

Which I think further speaks to my point I made elsewhere in this thread, that a huge part of the problem is that the web itself is shittier. Chrome can just handle that shittiness a bit better by default.

I would love to see a comparison of Firefox vs Chrome with the same set of uBlock and NoScript rules applied to both. I suspect Chrome would probably still win, but perhaps the gap won't be as big.
