The Thunderbird add-on prompts for a master password during startup.
It's important to keep in mind that although this add-on can improve security, it cannot fully secure your account. This is because extensions can be easily disabled, for example, by running the application in safe mode. However, if you still wish to use StartupMaster, you can cancel the password prompt by default by enabling the relevant option in the extension settings.
Lastly, it's worth noting that if you understand the security concerns and still wish to use the add-on, you can force the application to quit if the password prompt is canceled. This can be done by enabling the relevant option in the extension settings. Overall, StartupMaster is a helpful add-on for those looking to streamline their login process in Thunderbird.
