You are right. My point is that you have to take steps to close tabs, if it is just "explicitly closing Firefox". On Desktop, the browser will be terminated on shutdown. Shutdown does not apply to phones. If I want to close all tabs the second I lock my phone - no such thing. It would be enough having a "Stop all Apps&Tabs at 12am" feature. This is really why I avoid browsing things on my phone at all, or use self-hosted progressive web apps that run in dedicated tasks. Btw. - can someone explain why my initial comment is downvoted - Is it because my use case appears ignorant or unusually extravagant?
