Every time I upgrade firefox, I see this in the yum output: /var/tmp/rpm-tmp.41922: line 11: cd: /usr/lib/xulrunner-1.9pre/extensions: No such file or directory The last time I saw this, I had xulrunner-1.9-0.beta2.18.nightly20080210.fc9.i386.rpm. There's no /usr/lib/xulrunner-1.9pre/extensions directory listed in the xulrunner RPM, so I'm not sure firefox thinks it should be there. This has been going on for a while.
