That's essentially how I've been A:B testing as well. I was hoping you had some software that measured power draw and tracked it. Much like the Windows 10 power usage info. A laptop fan is a pretty good arbiter. Agreed though, it's very noticeable and I never did feel it until I started using a laptop more than a desktop. I'm also finding bugs in the iOS version of Firefox which is probably going to be the last straw, not only does it freeze often, my bookmarks are no longer there and they were synced from my Firefox account. I'm likely to migrate to native browsers for whichever platform I'm on at that time. As you said in their own process they're focused on feature development but not efficiency. Overall, I'm losing faith that Mozilla has the resources to effectively manage all of this.
