Firefox 'CPU Resources' Issue Better But Not Gone

Although CPU utilization is noticeably better on newer versions of Firefox, it seems there are still a handful of people out there with issues. What about you?

I wrote about this last November after I had been grappling with this issue for more than a year. First, on an Hewlett-Packard business ultraportable and then on the Apple MacBook Air. As I stated at the time, my theory is that many users don't notice Firefox CPU utilization on large, well-ventilated mainstream laptops. But it can be an issue on ultraportables, which are more sensitive to heat because of the obvious design constraints (typically under an inch thick).
