Are you exiting before restarting your computer? You should do that and you should use the exit command (either in the menu or the keyboard shortcut). I suggest you also allow enough time for the process to finish before restarting the computer.

Also check that you have NOT selected Settings > General > Startup > Open previous windows and tabs [right at the top of the page].

This is easily the stupidest user experience problem I've ever seen, if this is the only way to get expected behavior to occur. I have never met anyone who individually closes every application they have running before shutting down their computer, and even if someone does, I defy you to show me a single person who does it by opening each application window and locating the exit menu option or using the keyboard shortcut, instead of just pressing the close button on the title bar.

I ended up replacing all of the files that Firefox uses to store session data with empty files, and then doing a quick "chmod a=r <file>". This works beautifully, but I shouldn't have to do this to get a browser to stop doing something stupid.

Terry here has put forth the official (terrible) solution, which, while functional, is absolutely idiotic and a complete failure on mozilla's part.

It is pretty common sense to completely close a application(s) before you shut down your OS or that applications(s) could crash or have issue next time you start it.

You have been lucky if you have not had noticeable issues till recent.

Is set to false by default and is still set to false. You were saying?

Oh charming. It updated my file permissions too. Mozilla be acting like Microsoft with its forced functionality. It's a bad look, especially for a linux client.
