Firefox 3.0.10 memory leak at certain webpages

Hi....
Whenever i go to certain download .cnet .com websites such as
http://download.cnet.com/Naviscope/3000-2356_4-11825.html
firefox immediately goes into overdrive with cpu usage and memory leaks to over a gig and stops responding.I then have to end the firefox process with task manager.Ive disabled admuncher ,avast ,and geswall and it still happens so i dont believe its them.Im usung outpost pro ,and before that rising firewall.It happens with both firewalls so i dont believe its the firewall causing the problem either.The g/f using her sony vaoi laptop has no problems with the urls.I have a dell laptop and a dell tower,and have the problem on both machines so wonder whther its a dell thing?.Ive also run firefox in safe mode without addons and it still behaves the same.The link works fine in IE 8
