Perhaps I should if I'm going to echo > these claims of a leaner firefox :-) I decided I could do a very simple test. I'm aware that top is not the most accurate reflection of RAM usage, but it's what I'm using here nonetheless. I opened firefox and then sequentially opened 5 more typical tabs to see what the RAM usage was in firefox-2 and firefox (v3) on a hardy machine. I'm embarrassed to say that based on this simple test, there's little or no measurable difference. I'm not sure this isn't too simple a test, but I can't as yet offer any evidence for firefox v3's supposed superior ram usage -- though I do think it's functionally better (the predictive url bar in particular is brilliant). Curiously CPU usage appears lower, but that's a fluctuating value, so I couldn't say that with any confidence.
