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 Jul 20 12:05:52 Updated: firefox.i386 1.5.0.12-3.el5.centos Oct 24 07:30:46 Updated: firefox.i386 1.5.0.12-6.el5.centos Dec 05 09:39:13 Updated: firefox.i386 1.5.0.12-7.el5.centos [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 Jul 20 12:05:52 Updated: firefox.i386 1.5.0.12-3.el5.centos Oct 24 07:30:46 Updated: firefox.i386 1.5.0.12-6.el5.centos Dec 05 09:39:13 Updated: firefox.i386 1.5.0.12-7.el5.centos [root at mavis log]# grep -i firefox\* /var/log/yum.log.1 Feb 10 07:48:31 Updated: firefox.i386 1.5.0.12-9.el5.centos Mar 28 08:12:17 Updated: firefox.i386 1.5.0.12-14.el5.centos Apr 19 11:19:13 Updated: firefox.i386 1.5.0.12-15.el5.centos Jun 24 16:53:06 Updated: firefox.i386 3.0-0.beta5.6.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.
