when i surf on firefox and also working on visual studio 2005, i try to download few images, i found that firefox uses 100 % cpu after around 10 to 20 image download (approx) at that time i need to kill all the other application running. but still firefox uses 100% cpu , and take long time to come to normal cpu usage.
i checked the memory usage also it goes upto 64mb to 70mb. so i cleared all cookies,caches but still it memory usage is not coming down.
this problem i observed while using and also.
why firefox uses this much of memory? and whether there is any way to reduce 
memory usage and cpu usage

Reproducible: Always

Steps to Reproduce:
1. running microsoft visual studio 2005 pro
2. downloading images from www.maximonline.com
3. try to download more no. of images

Expected Results:  
cpu usage goes to 100% for firefox, memory usage goes  > 60mb

when i close all the tabs then memory usage should become normal
Does it do the same thing with a new firefox profile?
