FirePasswordViewer is the GUI version of popular FirePassword tool to recover login passwords stored by Firefox. Like other browsers, Firefox also stores the login details such as username, password for every website visited by the user at the user consent. All these secret details are stored in Firefox sign-on database securely in an encrypted format. FirePasswordViewer can instantly decrypt and recover these secrets even if they are protected with master password. Also FirePasswordViewer can be used to recover sign-on passwords from different profile (for other users on the same system) as well as from the different operating system (such as Linux, Mac etc). This greatly helps forensic investigators who can copy the Firefox profile data from the target system to different machine and recover the passwords offline without affecting the target environment. New version brings in the Installer to locally install FirePasswordVieweer on your system. It has intuitive setup wizard which guides you through series of steps in easy Installation as well as Uninstallation. FirePasswordViewer is fully portable tool which works on wider range of platforms starting from Windows XP to latest operating system, Windows 7.

About Firefox Password Manager
Firefox has a built-in password manager tool which stores username and passwords for all the visited websites. These credentials are stored in the encrypted form in the Firefox profile's database files such as key3.db and signons.txt.
The key3.db file contains master password related information such as encrypted password check string, salt, algorithm and version information etc.
Signons.txt file contains the actual sign-on information
Reject Host list : List of websites for which user don't want Firefox to remember the credentials.
Normal Host List : Each host URL is followed by username and password.
Internals of FirePasswordViewer Firefox till version 3.5 stores the sign-on secrets in signons.txt file located in the Firefox profile directory. With version 3.5 onwards Firefox started storing the sign-on secrets in Sqlite database file named 'signons.sqlite'. The structure of sign-on information stored in the signons.txt file (signons2.txt for version 2 and signons3.txt for version 3) and signons.sqlite for version 3.5 onwards is described below...
For Firefox < version 2.0
First comes the sign-on file header which is always "#2c" Next comes the reject host list in clear text, one per line and terminated with full stop. After that normal host list is stored in the following format Host URL Name (username or *password) Value (encrypted) .(full stop)
For Firefox version 2.0
First comes the sign-on file header which is always "#2d" Next comes the reject host list in clear text, one per line and ends with full stop. After that normal host list is stored in the following format Host URL Name (username or *password) Value (encrypted) Subdomain URL .(full stop)
For Firefox version 3.0 and below 3.5
First comes the sign-on file header which is always "#2e" Next comes the excluded host list in clear text, one per line and ends with full stop. After that saved host list is stored in the following format Host URL Name (username or *password) Value (encrypted) Subdomain URL --- (Dashed line denoting the end of host entry) .(full stop)
For Firefox version 3.5 and above
The new signons.sqlite database file has two tables moz_disabledHosts and moz_logins. The moz_disabledHosts table contains list of excluded websites which are exempted from storing passwords by user. The moz_logins table contains all the saved website passwords. Here is more detailed description of each tables...
table - moz_disabledHosts id - index of each entry hostname - blacklisted website URL
table - moz_logins id - index of each entry hostname - base website URL httpRealm - formSubmitURL - Actual website hosting URL for which secrets are saved. usernameField - name of username element of form field passwordField - name of password element of form field encryptedUsername - encrypted username encryptedPassword - encrypted password guid - unique GUID for each entry encType - value 1 indicates encrypted
Here each Host entry can have multiple username/password pairs. Starting from Firefox version 2.0, sub domain URL is also included along with username/password entry. If it is the password field then it begins with '*'. This is the key in distinguishing between username and password entry.
Now once the username and password values are extracted, next task is to decrypt them. Information required to decrypt these values is stored in key3.db file. If the master password is set, then you must provide the master password to proceed with decryption. If you have forgotten the master password, then you can use Firemaster tool to recover the master password. If the master password is set and if you have not provided it, then FirePasswordViewer will prompt you to enter the master password.
Though FirePasswordViewer is a Portable tool, it comes with Installer so that you can install it locally on your system for regular usage. This installer has intuitive wizard (as shown in the screenshot below) which guides you through series of steps in completion of installation. At any point of time you can use Uninstaller to remove the software from the system.
