Yes, please try this before we can say we give up. :)

I believe it is not always a correct assumption that an old package must 
be a left over from the upgrade. There are sometimes packages in the 
release carried over from the previous release.

A small correction, livna still exists and carries exactly one package, 
libdvdcss. It is necessary for playback of commercial encrypted DVDs.

>> I am not sure I mentioned it before, but I installed another, newer, version of firefox. It is a different version , from mozilla.org, that installs in my home directory instead of on the system. So far that works fine in parallel with the yum installed version (which still doesn't work).

My system is a mess with 3 hard drives, grub boot record installed on /dev/sda and the grub files on sda8, but I run fc12 from /dev/sdc7. I have two versions of ubuntu, puppy, and another fc12 installed and keeping up to date is just too complicated.
