I’ve long found it shocking the extent to which Google and Mozilla shrug this aspect off. Between laptops, phones, and tablets, computing is dominated by battery powered devices… power efficiency should be a headlining goal, not a trailing afterthought.

As a user I don’t care nearly as much if my browser supports WebOnions v2 or whatever feature-du-jour as I do that it’s not wantonly burning through my battery just doing basic browsing.
