so to help you understand this issue you need to understand that i have configured firefox to always delete site data cookies history etc when closing firefox, but recently my machine crashed and when i reopened firefox it saved the previous session, this can be an issue if you're on a shared machine or not on a trusted device, this issue can be dangerous or problematic in some scenarios, and i wonder if the same issue can be found on tor browser since it's built on firefox which can be very dangerous.
