Sounds like Firefox is thinking it crashed when it was last closed, and so is automatically trying to restore the session which was running before the crash. I'd think there should be a way to prevent this auto-restore, but given the settings you've said you already have in place, I don't know what it would be. A bit of quick Googling suggests that the advanced preference browser.sessionstore.resume_from_crash may control the behavior, but I can't say for certain. Why Firefox is crashing (or closing in a way which it thinks is a crash) is another question. I often see a duplicate "browsing session" and "crashed session" in my session-history list, so the problem may be happening here as well - but since I _want_ Firefox to restore tabs (and have it set to prompt me for which session to restore, via an add-on for the purpose), I've never had cause to dig into it. I too launch Firefox (or rather, Iceweasel; I'm still on 38ESR, and have seen my probably-the-same-issue symptom since at least 31ESR if not 24ESR) from a window-manager menu, although I run Enlightenment DR16 (locally built, since I keep not getting back to my effort to package it for Debian again) rather than Xfce. Once upon a time I did habitually launch it from a terminal window, but that was years ago, and I don't know whether the problem happened back then. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
