If you have forgotten login passwords to your favorite sites, then there is nothing to worry about. You can still recover the passwords stored in the Mozilla Firefox web browser. There is a freeware tool called PasswordFox that lets you view the the user names and passwords stored by Mozilla Firefox Web browser. You can view the passwords stored in your default Firefox profile as well as other user profiles.
You can download the PasswordFox utility from the NirSoft website. The download is a portable application which does not need to be installed on your system. Just download the ZIP file, extract its contents to a folder and run PasswordFox.exe from there. It will load the default Firefox profile and show you the login passwords stored inside it. It shows the website name, username and password for each entry along with some other data.
If you want to view the passwords stored in some other Firefox profile, then you can click on the open button in the toolbar and select the full path to that Firefox user profile. You can also specify the master password (if that profile is protected by one). There is an option to load the selected user profile next time you start PasswordFox.
PasswordFox also gives you options to save the detected passwords in form of text, HTML, XML or CSV files. This way you can not only view but keep a backup of your login passwords in Firefox. It must be mentioned that keeping the copy of your login credentials in plain text files on your computer is a security risk, therefore you should encrypt the files (using a tool like AxCrypt) if you want to keep the passwords stored inside them.
