[Bug 38131] Re: Firefox causes massive Xorg CPU usage

[Nigel Ridley]

Kubuntu Hardy Heron 8.04
Dell Inspiron 1525 Intel graphics (x3100)
Both Firefox 3 Beta 5 and Firefox 2 are affected.

I managed to get Firefox behaving by installing the 'Adblock Plus' extension and blocking most of the 'Flash' ads.
http://www.ynetnews.com/ was terrible - just loading the page would cause massive cpu cycles and the stepping on the dual-core to jump to 2001 cpu's. It would then settle down to 800 cpu's and then up to 2001 cpu's again. This would happen constantly whilst viewing said web page. If I attempted to scroll the page a few times at a go, then Firefox would stop responding for a while.

My understanding is that sites that have several 'Flash' ads or content
cause the problem. It's not 'Flash' of itself, I have no problem viewing
'youtube' videos, it's just multiple 'Flash' content that causes the
problem.
