I'm trying to just close and restart firefox from some bash scripts on Linux so that I can manage a few items from various hotkeys. I'm trying to close an existing Firefox process "cleanly", and am running into issues with how to kill the Firefox process and have it restart without showing the "restore session" page. If I update about:config and override "browser.sessionstore.resume_from_crash" to false, then I get the behavior I'm looking for, but I'd rather not have to override this. I've tried multiple kill signals from the `kill` command, including HUP, STOP, QUIT, TERM, INT, however all of them seem to trigger the same behavior. So is there a way to cleanly close (or restart) Firefox from the terminal?
