When I am visiting flash sites, I notice that Firefox becomes unresponsive and the memory and cpu usage jumps up high.

The memory usage gets higher and higher, and the Firefox.exe process ends up using a ridiculous amount of memory. 

I have 1gb ram, and it ends up using close to 700MB, when only one tab is open, viewing a Flash webpage.

Reproducible: Always

Steps to Reproduce:
1. Run Firefox with no tabs open
2. Open a website which has Flash embeddeded into it

Actual Results:  
Computer cpu and memory usage spikes. Long freezes that cause Firefox to become unstable.

Expected Results:  
Flash should render correctly and there should be no significant slowdown when viewing Flash webpages.

Same problem using firefox in XP. When flashplayer is on, firefox eats lots of memory and cpu; opening more pages with flash - freeze. I had firefox 2 untill few days ago and worked fine for years from the first time on this pages, i did`t upgrate to 3 because when 3 had become available i installed on several computers and... same problem. Youtube forced me now to change to 3, i thaught the problem was solved :(. I am using ie now if i want to go on multiplayer online games (i can use firefox but i have to keep only one window opened else my computer freezes)
Do you still see this problem in newer versions of Firefox? Or in safe mode with addons disabled?
Could you give us more detailed informations?
