Although the option to "Delete cookies and site data when Firefox is closed" is unchecked in my settings, I am still getting logged out of all websites when Firefox restarts. This was never the case when I used Safari, and it's quite inconvenient to have to log in to so many websites all over again, especially when two factor authentication is required for many of them.

Is there anything that might be causing this, anything I can check or do on my end so that I am staying logged in on restart? Thank you.
