The dump man page for 6.2 says:
Directories and regular files which have their ``nodump'' flag
(UF_NODUMP) set will be omitted along with everything under such
directories, subject to the -h option.
So if the "Cache" directories themselves are flagged, I think you'd be
chflags nodump /home/*/.mozilla/firefox/*/Cache
(without the -R) would be a good thing to quickly make sure the
directories are flagged in case the users delete/recreate the Cache
folders, but wouldn't take as long as flagging each and every cache file.
You'd probably also want to add "-h 0" to the dump args, otherwise the
cache files would be included in level 0 dumps.
