My Firefox is running just fine, too, Lanny. Seems like I recall the 
O.P. having problems with cross-pollinated repositories some time ago. A 
Firefox update history might be helpful:

    [root at mavis log]# grep -i firefox* /var/log/yum.log.2
    Jun 27 20:27:40 Updated: firefox.i386 1.5.0.12-1.el5.centos

    [root at mavis log]#

Also, it might be useful to remove all addons -- extensions, themes, 
plugins, etc. to see if one of those is causing a problem.
