After modifying the plugins configuration file, the one "active" plugin
entry leads firefox to search flash in:
/usr/lib/mozilla/plugins/libflashplayer.so
Is there a valid library? (you can run $ls -l
/usr/lib/mozilla/plugins/libflashplayer.so to find out)
If not, which is what I suspect, try to create a link from
/usr/lib/mozilla/plugins/libflashplayer.so to
/usr/lib/flashplugin-installer/libflashplayer.so (run $
sudo ln -s/usr/lib/flashplugin-installer/libflashplayer.so
/usr/lib/mozilla/plugins/libflashplayer.so)
