I run mostly with my laptop closed and two external monitors and the only time FF makes the fans run is one particular site (dailykos.com) which seems to make the CPU go nuts.
Otherwise, I've always been on FF from the Netscape days. I use Chrome when I have to (noticably Hangouts for a while), but otherwise stayed with FF without a problem.
