Hi all,

Can someone assist me to sort out a 100% CPU usage by FireFox. It
happens with all 3.X versions. FF is unusable at the moment. I have
searched and see that it has been a problem in most FF versions and
Linux. I need an urgent fix. Our ERPII system uses Web Browsers (Web 2.0
& LAMP). The Windows users with M$IE have no problems, but it is banned
in our company.

System: OpenSUSE 10.3
Linux ~ 2.6.22.19-0.1-default #1 SMP 2008-10-14 22:17:43 +0200 x86_64
x86_64 x86_64 GNU/Linux
FireFox:
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.5) Gecko/2008121300
SUSE/3.0.5-2.3 Firefox/3.0.5

Your report misses quite a bit of technical information.
The only really known thing is that the sqlite use for history and
bookmarks can slow down Firefox quite a lot (not sure if it uses 100%
CPU since usually it's just IO bound).
That depends also on the filesystem used for the profiles.

If it turns out that is your issue you can try to improve it by setting
the pref
pref("toolkit.storage.synchronous", 0);

So if that isn't your issue, we need for sure much more information.
