Can't to start Firefox

Hi to all.
I am linux newbie. I have installed and updated my openSuse 12.1 KDE, but Firefox don’t want to start :frowning:
If i try to run it from terminal, i have this code:

Gaml3t@linux-hcxq:~> firefox
XPCOMGlueLoad error for file /usr/lib/firefox/
/usr/lib/ invalid ELF header
Couldn't load XPCOM.

I hope you will help me. Thanks a lot!

How did you install, how did you update? Please open a terminal window, invoke command below, and post output here, between CODE tags:

zypper lr -d
