I got tired of all that symlink nonsense a long time ago, and made this
function to do the update:
[ -e "${HOME}/.mozilla/plugins/npwrapper.libflashplayer.so" ] && unlink
${HOME}/.mozilla/plugins/npwrapper.libflashplayer.so;
nspluginwrapper -i
/usr/local/lib/npapi/linux-f10-flashplugin/libflashplayer.so
hth,
