Thunderbird Password Decryptor is a handy utility for those of us with multiple email addresses and yet has forgotten one or more passwords. I have done numerous repairs where the person does not know their email password even after I told them to write it down. Guess that explains why so many people use such simple passwords. The zip file comes with an installer and the portable version. You simply drag and drop (or locate) your Thunderbird installation folder and profile folder, usually under Thunderbird, Data, profile and enter your master password (if used) and click start recovery. You are then shown your mail server name, username, and password. Personally, I have used Mozilla Thunderbird Portable for years now because all you need to do is keep a backup copy of the folder somewhere, and your email will always work, from anywhere. But, for those who use the installation version of Thunderbird, this may come in handy.Thunderbird is a free, open-source, cross-platform application for managing email and news feeds. Like other Email applications, it also stores the mail account passwords on the local system for subsequent logins so that user don't have to type the password every time.'Thunderbird Pass Decryptor' helps in instantly recovering all such stored Mail passwords. You can also use it to recover the Thunderbird account passwords from another system.It comes with Installer to help in local Installation & Un-installation of software. It works on wide platforms starting from Windows XP to Windows 8.
