firefox crashes!

I have a problem with mozilla firefox.
It runs in a very tiny window. If I try to enlarge it this windows does not contain anythink, it’s just a blank window only with the X button to close. If I close it Firefox crashes without any output message.

Can anybody help me?

Thanx

delete firefox and install it new, maybe that would help

Start it from Konsole (Terminal) and post here the output messages.

no output messages running mozilla from konsole!
I tried to reinstall mozilla from yast but nothing changes. Should I try to uninstall it completely? and what about the config files? they will be deleted too?

Profile will stay as will other conf files in home directory (most apps don’t delete it as it might come handy later)
