Yesterday after upgrading my system I tried to run firefox, but the button icons show a blank document icon with an ‘x’ in the centre. The terminal output was something like this (cut short for the word limit):

Please help me as I am new to linux. Thank you.

This indicates that you have an invalid mix of 32bit and 64bit packages.

From which version to which version did you upgrade? And how? (DVD, “zypper dup”, …)
Did you try to upgrade a 32bit system to 64bit or vice versa?

Please show the output of:

uname -a
zypper lr -d
rpm -qa | grep gdk
