In case of liferea, the dependency is not actually that hard-coded.
liferea uses LD_LIBRARY_PATH to add Firefox's installation directory
before calling the actual liferea-bin binary. This path is detected at
build time and hardcoded into the script.

In liferea's case, yes, the problem would go away if the last version
of Firefox installed would just create a symlink of
%{_libdir}/firefox-%{version} to %{_libdir}/firefox

In an ideal world, Fedora Core and Extras packages would get
automatically rebuilt if their dependencies would be broken by an
update. As I understand it, such rebuilds are now done by hand?

Don't worry about avoiding temptation -- as you grow older, it starts
