Mozilla, Firefox and Thunderbird have comfortable password managers, but if you compare them to the Protected Storage of IE or WAND of Opera, the latter ones are more powerful and functional.
Mozilla Password Recovery is a small utility that reveals the Autofill passwords for Firefox, Mozilla and SeaMonkey, as well as the account passwords of the Thunderbird mail client. The program traditionally offers you two recovery modes: automatic and manual. With this utility, you can also recover passwords protected with the User Master Password. It can as well view browser Cookies and URL history.

System Requirements: Mozilla 1.x, SeaMonkey 1.x, Firefox 1.x-3.0, Thunderbird 1.x-2.0

System Requirements: Better profile detection for Firefox, Netscape, K-Meleon, Thunderbird, Beonex, SongBird and Flock.
