This is a common problem I've been experiencing recently on a completely update FC3 distro. In firefox when a flash advertisement is shown (i have a 3GHz intel CPU) the cpu usage will jet up to 100% as shown on my applet on top of the gnome bar. If I scroll down to the bottom of the page where the advertisements can't be seen then the CPU goes back to normal. It's very worrying. What could possibly be going on?
Say the flash advertisements on this page (but really anywhere): <http://imdb.com/title/tt0401792/>
I've had to kill firefox processes every once in a while because they had literally brought my computer to a standstill.
Anyone had a similar problem?
