Firefox 30. When I exit it - it briefly shows a message "Firefox is now closing...". Is there a way to stop this behavior - it is annoying!

When you are in Private Browsing mode then no personal data is saved to disk and that means that all cookies automatically expire when you close Firefox.

type in the address bar: about:config then search for browser.showquitwarning and double click on it to set its value to false

close the about:config window and see if it happens again

It actually tells me that it is deleting cookies. The browser.showquitwarning is set to False. I have the browser set to always use Private Browsing mode and keep cookies until I exit. Thank you for the quick response.
