In Firefox, using the FireFox-CredentialSelection SecureLogin is unable to populate the selected credential set in the FireFox authentication dialog.
Manually insert a dummy win32 application definition called firefox.exe.
SecureLogin will not populate the selected credentials if the application definition firefox.exe application definition does not exist.
SecureLogin will create the FireFox.exe application definition after the user enters the credentials the first time. Thereafter, SecureLogin will populate the single sign the authentication dialog.
