 I don't have machine with full FC6 installation, but you can create
 the list very easily by shell command:

 for f in `cat /etc/readahead.d/default.*`; do rpm -q --queryformat "%{NAME}\n" -f $f 2> /dev/null; done | sort -u

 The problem is not firefox only. It's pretty generic problem, because
 we have versions filenames for libraries:

 $ grep '/usr/lib/lib.*[0-9].*' /etc/readahead.d/default.*  | wc -l
 136

 It's means almost all things in /etc/readahead.d/default.* could be
 obsolete after an update (except stable things like /bin/*).
