output of strace -o strace.log firefox
Couldn't load XPCOM.

the only file under /etc/gre.d is gre.conf

sudo cat /etc/gre.d/gre.conf
[1.9.1.9]
GRE_PATH=/usr/lib/xulrunner-1.9.1
xulrunner=true
abi=x86-gcc3[donvogt at localhost ~]$ 



I am running  kernel 2.6.32.10-90.fc12.i686 on a i686 athlon
I have no mixed libraries

I apologize for my screwed up messages. My excuses are
1. I am an old man
2. I just had some tooth roots extracted
3. I am on codiene for the pain
4. I use digests and find replying to several messages at the same time confusing. 
5.No excuse sir. I will try to be more careful. (I have stopped the codiene.)

I really appreciate the help. I am well above my depth here.
