Si no se establece una contraseña maestra, Firefox usa una contraseña vacía.
Para un script Python sucio para descifrar y volcar los datos (y algunos más), consulte el siguiente código. Es un viejo proyecto mío y acabo de actualizar la lectura de las contraseñas y los nombres de usuario que se guardaron en signons.sqlite antes (ahora en logins.json ). No puedo garantizar que (todo) esté funcionando, pero lo hizo en mi caso de prueba.

# Some little firefox forensic script delivering following data:
# - saved passwords (decrypted if no master pw is set)
# - visited pages
# - download history
# - form history
# - cookies
#
# TODO:
# - flash cookies and stuff
# - finish comments
# - add little brute forcer for master pw
# - dump master pw ?
# - add some more compatibility stuff (mac if requested, else fuck it)
# - use some user defined exceptions instead plain exception
# - cache
# - think about which data from the db to return ;)
#
# ATTENTION: On my win7 system i needed a newer sqlite version.
# see http://code.activestate.com/lists/python-tutor/96183/
# - easy (and dirty) solution: get new sqlite.dll, replace in ...python/DLLS/
