Have you ever forgotten your password when you tried to log on to a Web site? We thought so. Like many Web browsers, Mozilla's Firefox saves your password, username, and other log-in details for every applicable Web site and stores the data in its sign-on database. FirePasswordViewer is a free tool that can decrypt, recover, and display this data. It will show a site's password on the same line as the username in Firefox's built-in Password Manager when you click Show Passwords. However, it can also display your passwords in its own interface, even when Firefox isn't open. This makes it possible to recover a password even when Firefox won't open.

FirePasswordViewer's download comprises both installed and portable versions; we tried the installed version. It's a simple tool that automatically identified and displayed the installation and user paths for our copy of Firefox, though we could also browse to different directories, such as another user's account or a separate Firefox installation. There's a field in which to enter a Master Password if one is needed. We clicked Start Recovery, and FirePasswordViewer quickly scanned Firefox's database, displaying the results by Web site URL, username, and password, with password entries in asterisks. Clicking the Show Passwords button revealed the passwords. Another button let us save the results in an HTML file. Other than that, there's just a Close button and a link to the site of the developer, SecurityXploded.

FirePasswordViewer adds a GUI to an existing tool, making it easier to use and thus more accessible to the millions of Firefox users. As strong passwords with mixed characters become both more common and more necessary for safe surfing, a simple tool like FirePasswordViewer becomes ever more useful.
