Breezy upgrade: Firefox cpu problem

[Florence Berbain]

Hi all,

A few days ago I upgraded a spare computer from Hoary to Breezy. The 
upgrade seemed to go ok, however the machine is now very sluggish. The 
problem seems to come from Firefox: whenever I launch Firefox, top 
reports it's eating up 90% CPU or more (this happens as soon as Firefox 
is started, and not after several hours/days of use as I've seen people 
report in other threads). It uses 7% of the memory.

Otherwise, the machine behaves normally (that is, as I remember it did 
under Hoary, even though I haven't used it since last June. But I'm 
certain I was able then to run Firefox, Thunderbird, and emacs at the 
same time with no problems at all). The machine is a P3 550 Mhz with 
784M RAM, shouldn't that be plenty enough for Breezy (with Gnome)?

I uninstalled and reinstalled firefox in synaptic, with no result.

BTW do I need the packages firefox-gnome-support (I am using Gnome) and 
mozilla-firefox?

Thanks for ideas,
Florence
