Firefox/Mozilla/SeaMonkey Password Recovery - Autocomplete Data Viewer
Mozilla's Autocomplete feature remembers and saves previous entries you've made for Web addresses, forms, and passwords. Then, when your type information in one of these fields, Mozilla/Firefox/SeaMonkey suggests possible matches for this field. These matches can include your typed in data, stock quotes, search queries, or any other personal information you have ever filled in on a Web page, even your credit card numbers.
Autocomplete data viewer is a feature to decrypt and view the autocomplete data for Web pages and forms you've ever saved in your Firefox/Mozilla/SeaMonkey browser. With this feature you can as well remove your personal information if it is not needed anymore, to prevent yourself from being a victim of a potential hacker.
First, you'll have to set up your browser's profile folder (one with the formshistory.dat file in it) or select one from the drop-down menu. The profiles folder may look like this:
Firefox:
C:\Documents And Settings\%USERPROFILE%\ApplicationData\Mozilla\Firefox\profiles\%PROFILEFOLDER%
Mozilla or SeaMonkey:
C:\Documents And Settings\%USERPROFILE%\ApplicationData\Mozilla\default\%PROFILEFOLDER%

After setting up a profile folder, click Next to decrypt and view your browser's autocomplete data.
