I'm running Firefox 8 now since it came out last week.
Not only did I find it to be slow (compared for both, FF7 and Chrome), but also a real memory hog.
~800MB on my work laptop, with only 6 tabs open, and really not responsive at all.
FF7 and earlier never had more than 300-400 MB (roughly) on that machine - with the same tabs and apps open, and the same extensions installed. So this was odd.
Especially start-up was a catastrophe.
Then, yesterday, I got the slow-script warning for sessionstore.js.
Well that about just did it for me ...
I went to my profile directory[1], and found a sessionsstore.js with more than 3MB.
I renamed it, restarted FF... of course with none of the pinned app-tabs open, because I took the session store away... But that's what I wanted.
I manually re-established my pinned app tabs, and voila
FF8 now was back to using 250MB, and the sessionstore.js was around 200kB
So - fixed for now. I think I had the session store build up for more than 1 year now and never cleared it (and quite frankly, why should I). So maybe cleaning it once might really fix the problem, and FF8 is not such a memory hog after all - or maybe it will be back after a couple of months...
Let's see, how this progresses from here...

I got the same issue, it eating up a huge amount of memory even when you close all the tabs and leave one (Google home page) it doesn't clear the memory (in my case it is 1.4 GB all the time)
well, try to reset (=delete) the session store as described. just closing the tabs, does not do it, I'm afraid
