Comment 21 for bug 583797

I have

browser.tabs.warnOnClose = true
browser.warnOnQuit = true
browser.warnOnRestart = true

If I close a window with multiple tabs I get a warning dialog box. If I choose quit from the meny, I get no warning whatsoever. If I choose "restart Firefox" from the addon update window, I get no warning whatsoever.

If my privacy options are set to "Clear history at restart", even though I have all these options set to true, and even though I have an option stating "Start Firefox with the windows/tabs from last time", an addon/browser update, or a quit due to instability issues wipes out all my open windows and tabs with no hope of recovering them.

This really makes no sense to me, and there should be a safer way to ensure that the expectations of the developers and the users don't clash in this way causing loss of data.
