Mozilla Firefox Won't Start

Hello all. I could use some help as well. I just upgraded to Mozilla Firefox v-0.9.3 on one of my desktop PCs using SuSE's rpm, MozillaFirefox-0.9.3-0.1.i586.rpm. Now Firefox won't start. I'm sure the fix is very easy. I just can't seem to find the answer right now. As always, TIA for any/all help. Chris/CMS
