Comment (by sysrqb):

 Okay, the SessionStore does not write private tab data on disk, it only
 saves normal tabs. We used #28507 as a mitigation for normal tabs being
 restored when the app is restarted. This brings us back to #24920 because
 Fennec doesn't have an easy `browser.privatebrowsing.autostart` pref like
 we have on desktop.
