I posted this question in one of those huge FF3 threads and I think it got lost.

I wanted to see how everyone's RAM usage is now with FF3.

I jumped to using 1.59 G. I have nothing else open. In activity monitor my CPU usage is about 23%.
 
Currently, after keeping Firefox on for 6 hours and just browsing the web for several minutes and then going to sleep, my Firefox is using 122 MB of RAM.

I have 2 Gigs of RAM.

Also I have noticed that Firefox uses much less ram than safari but tends to use more cpu. For example, for the same youtube video playing on high quality, safari used 40-64% cpu while firefox used 47-90%.
 
Mine is using 167 MB of RAM. I don't remember FF2 using that much. I'll have to test it later.
