Bug#680095: iceweasel 10.0.5 consumes lots of CPU

[Mike Warren]

I see this behavior with Iceweasel 10.0.5 from wheezy as well. I'm
up-to-date as of right now, and starting with "iceweasel -safe-mode"
with one tab open consumes ~120% CPU (dual core macmini 3,1 with 8GiB
RAM).

I started noticing this "recently", which isn't to say it hasn't been
happening for a while but I usually have two running in two different
X sessions with somewhere around 120 tabs open and it has been pretty
unresponsive lately.

Any more information that would be useful?
