I've been running FF 2.0 for about a week now, and I've noticed things being very sluggish. RAM usage goes through the roof and my windows don't minimize smoothly anymore...by this, I mean when I click the yellow button the window decreases in a very jagged way. That's all I've got time for now. Let me know if anyone else has experienced such problems. I'm running 10.4.7 on a 1.83 Macbook w/ 2 gigs of RAM, btw. Thanks.
