I am. And granted its memory management is getting better with each release (memory usage improved greatly from 2 to 3). Admittedly, I haven't had 3.5 RC long enough for a very extensive experience. I'm speaking primarily of FF3, which for me could get quite painful even switching tabs (especially with Gmail open on one tab). It could be better, but 3.5 RC has only been out a few days. At first, I loved the shit out of FF3, but after a while, I found myself getting furious (at least working on my laptop; on my desktop, which is a beastly gaming machine, I don't have nearly as many complaints).
