I have an old notebook with a hardware profile like this :
cpu: Intel Celeron 1.5GHZ ram: 1G os : winxp sp2 browser: firefox 3.5.3
I found when I browse web pages with embeded flash ads or video clips, my firefox could eat up to 300M, 500M, sometimes even 600M memories. I experimented a bit and I can say I'm sure it's related to the flash embeded pages because this case doesn't happen when it's plain text with images pages. Also I'm sure there's no virus on my os.
What's the problem or is it just firefox ?
