No I don't have "delete cookies when Firefox is closed" enabled.

I had two power outages in a row and ever since then every time i close Firefox it removes every single login I had saved even though it keeps the 3GB of cookie data still. I have to copy over an old backup that I luckily had in the Firefox files thanks to Firefox itself creating a backup. Still every single time I close this god forsaken browser I get logged out of every single thing. What am I supposed to do leave my PC running 24/7 without ever closing a browser? Every other basic solution that you can instantly find upon googling something similar to the topic title I already tried so don't bother writing it here, such as "uncheck the delete cookies box" well that doesn't do anything when its unchecked but still deletes everything does it. Bug fix?
