A lot of laptops don’t even have fans, and as a Firefox user who has owned ultrabooks for the last several years, I can’t say that this choice of browser has had any noticeable detrimental impact; I still get the many hours of battery life that ultrabooks are known for. I suspect that the devs, faced with limited resources and the need to prioritize, would consider this a matter for the hardware and OS to deal with.
