CPU usage by Xorg process is very high while page is loading (constantly about
50-80%) if option "Tabs on Top" is off (by default it is on). You can change
this option in context menu of any panel. Disabling tab loading animation by
editing userChrome.css solves problem completely. It is reproducable on clean
profile of iceweasel. I've downloaded Firefox directly from Mozilla and bug is
not reproducable on it.

I'm using GNOME Desktop Environment (only part of it actually), Nvidia
proprietary drivers from debian package (version 270.30), and I have no
compositing enabled.

I have exactly the same problem.
Dmitriy, could you please give a bit more details (or some pointer) on
editing the "userChrome.css" file? There's no such file in my profile
directory and I don't like the "Tabs on Top" format much.

Please, check "chrome" sub-folder in your profile folder, there should be
userChrome-example.css.  You can rename it or copy to userChrome.css in the
same sub-folder. I don't remember exact CSS selector I used, an answer from
here seems to be correct:

If it is not, please search web.

Did it get any better with iceweasel 5.0?

I'm not really sure is it better or worse, but bug is still reproducible in
5.0-6.

I was experiencing this issue quite a while back, and still am in the
iceweasel 8.0-3 package in unstable. I was wondering if the people
currently experiencing this bug could report which graphics card drivers
they're using? My experience with downgrading certain drivers and
packages seems to suggest that it might be a bug with the Xorg propriety
nvidia drivers. So if you are or aren't using these, data points either
way would be appreciated :)
