how much can I trust firefox password manager
How safe is firefox password manager? Can you give us some information on this subject? Mainly focus on: how hard is it to crack the passwords on firefox password manager for a hacker? How are our data stored, i.e. which type of encryption, both in my computer and your Sync server?
Chosen solution
The names and passwords stored in logins.json are encrypted with an encryption key that is stored in the key3.db file. The master password adds an additional level to this encryption. If you do not use a master password then having access to key3.db and logins.json is sufficient to have access to the encrypted names and passwords by placing the two files in a Firefox profile folder. Make sure to use a password that is sufficiently strong, e.g. at least 10 or 12 characters and a mixture of uppercase, lowercase, numbers and symbols that can't be found via a dictionary look up by combining words and you should be safe.
