It's not murdering battery because it's "harnessing the full power of the CPU", it's chomping through almost 1% battery a minute on Mac while doing virtually nothing.

Apparently "vibrance" is one of the culprits and switching to the light or dark themes can help a lot. But yes, it's destroying battery compared to Safari for me. Which is a shame, as it's already my default on Windows.

Sounds like you should definitely file a bug.

there is one: https://bugzilla.mozilla.org/show_bug.cgi?id=1404042 — it was moved to being tracked for v58.
