If I were you, I'd uninstall the Firefox you have on your machine,
and install instead the SuSE 9.1 rpm package with YaST
you can find one there MozillaFirefox 1.0.7-0.2 i586 package
or MozillaFirefox 1.0.7-0.2 x86_64 package
After installing the rpm package, you must run firefox under root login, the first time, and only after that, under a user login.
I hope this will suit your need.
