StartupMaster is a Thunderbird extension that asks your master password every time you start the application before the main window is displayed. If there is no master password set, the extension does nothing.
YOU MAY CANCEL THE PASSWORD PROMPT BY DEFAULT. THIS IS NOT A BUG.
It is impossible to secure your account by installing an extension, because extensions can be disabled easily, e.g. by running the application in safe mode. If you understand the security concerns and still insist, you may force the application to quit if the dialog is canceled by enabling the relevant option in the extension settings.
