SUMMARY
Tabs persist on firefox despite **ALL** relevant settings that do this being disabled. Session restore on KDE is disabled, "Open Previous tabs on startup" is also disabled in firefox settings, and when I restart/shutdown/logout and re-enter the system, all my tabs persist. I've turned off all the settings and this still happens.  

STEPS TO REPRODUCE
1. Have tabs open on firefox
2. Power off, restart, or log out of system
3. Tabs will persist

OBSERVED RESULT
Tabs do not get deleted when I reboot computer

EXPECTED RESULT
Tabs should be deleted when I reboot computer

This is going to be a Firefox bug, not a Plasma bug; there's nothing we can do to force this to happen like that. It's gotta be something in Firefox itself, or how you've configured it. Firefox has a lot of hidden settings; perhaps there's one being secretly used to restore tabs even though you've disabled the one visible in the settings window.
