Se non è impostata alcuna password principale, Firefox utilizza una password vuota.
Per uno script Python sporco per decodificare e scaricare i dati (più alcuni altri), vedere il seguente codice. È un mio vecchio progetto e ho appena aggiornato la lettura delle password e dei nomi utente che sono stati salvati in signons.sqlite prima (ora in logins.json ). Non posso garantire che (tutto) funzioni, ma è successo nel mio caso di test.

# 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/

Dovrebbe funzionare su Windows e Linux, ma ho appena testato le modifiche su un sistema Windows.
Modifica: ho sostituito lo script per decifrare le password con una sola per scaricare informazioni diverse (incluse password e nomi utente in forma decrittografata con una determinata password)
