Oh my god, that's hilarious. I was wondering why my lap was warm all of a sudden. Htop said firefox was the culprit so I closed out all my tabs except this one. Then I read your comment, opened the page, and scrolled all the way to the bottom—my cpu temp just steadily rose till it throttled. All the animations are smooth, though.
