Flash seems to be causing this, since it doesnt happen if you turn it off. I also see more cpu usage, but only 30-50%

Same happens on www.blesk.cz
All you have to do is open several pages in tabs and very quickly (not right away, give it a minute or two), firefox CPU usage goes to 97% and more. Then, when clicking on opened tabs, the browser does not switch to the clicked tab. The only solution is to terminate the Firefox session via W. Task Manager.
My system is Win XP SP 2.
