Firefox, Xorg, Facebook


Recommended Posts

Is anybody else seeing Xorg consume all available cpu cycles while veiwing Facebook? Think it's only started happening in the last week or so, but it's definitely Facebook that's causing it; switching to another tab will drop Xorg down to a reasonable rate. Disabling my extensions makes no difference and I don't have any desktop effects running. I am slighlty bemused as to why Xorg would be affected in this way anyway?

That is quite the anomaly, in my experience the only thing that ever gave my computer a little bit of a hassle (meaning just got the fans going) was extended Youtube viewing.

Could it be the excessive use of Ajax on facebook that causes it? try disabling javascript for facebook

It's actually X that is going crazy there? The base X Window system? Not the application (firefox/flash/etc), or the Window Manager/Desktop Environment?

Interesting. I will have to check that out and see what happens when I browse there on my fluxbox install.

... but, yeah, I can use NoScript to block Facebook and all is good, but I find it strange how it's Xorg that affected. Guess I'll have to see how useable FB is without scripts running.

I think I may have got this one. I've had a load of updates recently, and I was trying to think of something that may be somehow related to this. It was then that I remembered Flash was updated to 10 not so long ago, and possibly around the same time as I started having problems on FB.

Sure enough, reverting to Flash 9 seems to have solved this for me.

Yeah, Flash 10 is in Beta. It's pretty unstable so stick with version 9 for now until 10 is released

Facebook has been killing Firefox on me recently but I updated to the beta for 3.0.1 and it seemed to fix it. Although Firefox is running at 181mb right now according to top and that's only having one tab open.

Flash 10 also has caused major headaches for me on ubuntu 8.04. I reported it to them. Hopefully they will fix it (EX. toyota.com with flash 10 is unusable. on flash 9 is smooth as butter)

I just went on there now and it's fine.
