Bug#680095: iceweasel: Iceweasel consumes 50-80% cpu when idling

[Jerry Quinn]

Package: iceweasel
Version: 13.0.1-2
Severity: normal

Dear Maintainer,

I've seen this behavior in both iceweasel 12 and 13.  My normal browser has 60
tabs open.  When not doing anything, iceweasel consume 80% CPU.  Firing up a
clean profile and no tabs open still consumes 50% or more CPU.  Disablig all extensions and plugins doesn't change this at all.
