How can I get a warning of closing multiple tabs in private browsing mode?

I've changed the settings using preferences and about:config and I only get warnings of closing multiple tabs in normal mode, not private browsing mode. Also I do not have private browsing mode turned on by default.

What pref settings on the about:config page are you talking about? Is that the browser.warnOnQuit pref (others already default to true)?

  • browser.tabs.warnOnClose
  • browser.showQuitWarning
  • browser.warnOnQuit

There are a lot of cases that you do not get a warning when closing a window or closing the browser (File > Exit/Quit).

In PB mode then nothing is saved to disk and things may be different.

What is the startup setting?

  • Tools > Options > General > Startup: "When Firefox Starts":
    "Show my windows and tabs from last time"
    "Show my home page"
    "Show a blank page"

browser.tabs.warnOnClose = true browser.showQuitWarning = true browser.warnOnQuit = true

The startup setting is show my home page.

I get a confirmation when closing down windows with multiple tabs EXCEPT when I am using private browsing mode.
