Firefox stopping shutdown with question

Hello. When I go to shutdown with web pages open, Firefox produces a dialogue box asking whether I want to shutdown. Can I turn this feature off, so that Windows shutsdown Firefox without asking. Running Firefox 35.0 on Windows 8. Thanks.

Firefox will take some time to shutdown after you quit, because of tasks it may need to complete.

I am not a Windows 8 user, but presumably the warning is generated by Windows 8 because there are still Firefox processes running. Windows Task Manger would indicate whether that is the case.

Have you tried closing Firefox using its menu option,

  • USE: Menu Button {Three bar icon) -> Shutdown {off icon)

and leaving it a minute or two before closing down Windows.

I think over recent versions Firefox may have had some issues with its closedown, but probably most have been fixed. Please etiquettedo not post in Bugzilla it is a developers workspace not a discussion forum but as potentially related background information

  • Bug 916078 - (AsyncShutdown) [meta][Async shutdown] Make asynchronous services shutdown-safe

In fact IIRC some bug fix ensures that Firefox will itself eventually close all it's processes, but I can not seem to find that bug so I have linked to one of the tracking bugs.

You've probably got this checked - Options>General>Tabs>Warn me when closing multiple tabs.

You can check the 'warn' prefs on the about:config page.

  • browser.warnOnQuit
  • browser.showQuitWarning

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

No, it happened today when only one window was open.

Firstly, many thanks - a whole layer of preferencing I wasn't aware of.

I followed the suggestion. I made sure both of these settings were on false (one was already false). Restarted Firefox. Same warning. The screen says "This app [Firefox] is preventing shutdown". It's a timed warning as it continues shutting down after about ten seconds. Maybe it's Windows? To test, I had a Firefox and an IE browser window open (only one of each). The warning on shutdown only appears for Firefox.
