Firefox Password Storage:

There are two files involved in login and password storage in Mozilla Firefox:
1) signons.sqlite or logins.json - database with saved web addresses, encrypted user names and passwords.
2) key3.db (v. < 58) / key4.db (v. 58+) - database with encryption keys. Firefox Master Password protects keys stored in key.db.
Both files are stored in Firefox User Profile folder.
If master password is not set or is known encryption keys can be instantly extracted from database and used to decrypt saved logins and passwords.
If master password is set and unknown (lost) it has to be recovered first. Encryption methods used for master password protection are quite strong and its recoverability depends on length and complexity, however recovery speed is relatively high.
In order to recover these types of passwords, candidates have to be created based on dictionary, sequentially with a charset and length selected or as combination of dictionary, sequential (brute-force) and fixed parts. Firefox Password allows you to set several attacks in queue, split password in parts and set each part independently with virtually endless number of combinations. Additional modifications are available including unique keyboard layouts-aware recovery technique, char replacement (e.g. A or a with 4), etc.
