Is there a way to always make App Tabs the default on launch?

cor-el replied

I use the "show my tabs from last time" setting to have Firefox always launch a series of App Tabs. However, this feature is only beneficial when all other Firefox windows are closed first and the one with the desired settings is closed last.

Is there a way to make these App Tabs always the default when Firefox is launched? Meaning, regardless of when the Firefox window with the default App Tabs is closed, it will be the default when Firefox is next opened.

Use Firefox/File > Exit to close all open windows at once.
