Problems with Firefox

[Joerg Bergmann]

uname -r:
2.6.25.10-86.fc9.i686
Today, I got problems with updating. Obviously, the security updates
for firefox 3.0.1 could not be installed for some reason. I have gone
onto install/remove software and found firefox 3.0.0 or so installed.
I removed that firefox and tried to install 3.0.1. Got an error message
alike
Missing Dependency: gecko-libs = 1.9 is needed by
package totem-mozplugin-2.23.2-4.fc9.i386 (installed)
Missing Dependency: gecko-libs = 1.9 is needed by
package nspluginwrapper-1.1.0-2.fc9.i386 (installed)

At that point, I have no firefox installed. Seems I have to
re-install Fedora 9, or are there any hints?

Thanks in advance
