Monitoring my system with `top' I noticed that IceCat had a CPU percentage usage of 3%/6% even while idle! Restarting IceCat with -safe-mode and disabling all the extensions didn't give this results. I re enabled all the extensions one by one and discovered that the problem was actually `Priv3', which is installed by default with IceCat.
More details: Try doing: # strace -p `pidof icecat` both when `Priv3' is enabled and disabled. -- Cojocaru Alexandru -- http://gnuzilla.gnu.org
