I had the same issues and avoided FF 57+ because of it. I just tried FF 61 and my results were mixed. Twitch and Youtube still made my CPU temps spike a little bit. It seems worse than Chrome but better than FF 57.
Google Maps, unfortunately, still made my CPU temp spike 30C+ as soon as I opened it. I use Maps a lot, so this is still a deal breaker for me.
