"While Firefox 2 used less memory than it's predecessor, Firefox 1.5, we intentionally restricted the number of changes to the Gecko platform (Gecko 1.8.1 was only slightly different than Gecko 1.8) on which Firefox was built. However, while the majority of people were working on Firefox 2/Gecko 1.8.1, others of us were already ripping into the platform that Firefox 3 was to be built on: Gecko 1.9. We've made more significant changes to the platform than I can count, including many to reduce our memory footprint. The result has been dramatic."

In my experience, the only cpu-related problems firefox has had were when opening many new tabs at once (supposedly much improved in FF3) and in plugins. With 15-20 tabs open, Firefox 2 was basically unusable on my old machine with near 100% cpu usage. Then I installed AdBlock, which shut off all those Flash ads and cpu usage was back under 5%.

I know that this is strongly user dependant, but I have a measley 2Gb ram in my machine (cost all of £30) and I feel that Firefox has more CPU related issues than memory issues, not that I have any real performance issues with any of the current browsers. Even running in Virtual machines, I don't feel any issues.
