Firepassword is a tool which is used to enumerate the passwords saved in the Firefox password manager. This tool can be used to extract the credentials in plain text from the Firefox database and download it into a flat file for later use.
This tool has a huge advantage that this works in offline mode (no need to run Firefox) when compared to the password manager which comes with Firefox.
How to use
1. Locate the Firefox profile directory (If your firefox is a portable one, then find it in Dataprofile)
2. Copy the files bkey3.db, cert8.db and singons*.txt from the profile directory to a .
3. Open Commandprompt and type as shown below (replace the tmp_dir with the one mentioned in above step)
FirePassword [-m "master password" ] >> pass.txt
Options: -m specify the master password
4. Finds the passwords in plain text in pass.txt
Note: The steps mentioned above is for firefox 3, I’ve tested and got the expected results. Please check firepassword homepage for other versions of firefox.
