Multiple firefox crashes and flash loads CPU to max

[jonnybowes]

Binary package hint: firefox-3.5

Firstly when I play any video on youtube etc even only in a single tab my FF process jumps from 20% or so up to 50-60% thus my CPU gets maxed out and system grinds to a halt. I have notice browsing gets slower the longer I use it and the more tabs open(which i know would eat resourses)
But FF seems to crash randomly,on a variety of sites,open tabs...long short browsing time and sometimes takes 3/4 attempts to even get it started.

Please help

My problem is very similar to the original report of this bug. The web page that usually causes this is www.manager.co.th. This page contains some flash animation. Each and everytime I visit this page, I saw npviewer.bin starting to consume a lot of cpu usage, making the whole machine super busy. Since I am using a laptop, the fan starts blowing like crazy pretty quickly after leaving it on the page for a little while.

Something seems to be running too busily unnecessarily.
