Thats not really fair. When Chrome came out, it was bloody fantastic. It was WAY faster than FF, let alone IE. And still, whenever my linyx laptop starts behaving like a fan, I just kill FF - that will be the cause...
My dev-window will be in Chrome (local, no problem there), as is my Google account. Browsing I do via FF, but it will, very very often, hit 100% on a CPU.
