Even after enabling "Warn me when closing multiple tabs", firefox closes without any warning even if multiple tabs are open.
I recently installed Firefox 4.0 and in the options, under the section "Tabs", I have enabled "Warn me when closing multiple tabs". But if I have multiple tabs opened with websites loaded in them, and then try to close the browser, it simply closes. No warnings are shown (which was there in previous versions). Couple of times I clicked on the close button of browser and then realized that I had some important sites opened in different tabs, which I lost as it didn't warn me. Can you please let me know whether this is a bug or a mistake from my side?

One of the changes in Firefox 4: by default Firefox 4 does not display the "Save Tabs and Exit" warning message when closing multiple tabs, but it can be turned back on by changing some preferences.
- Saving tabs was not removed from Firefox 4, but it works a bit differently.
- By default, Firefox 4 will not ask to save tabs, but instead it will always save your tabs on exit. You can restore them next time by
- choosing "Restore Previous Session" from the History menu, or
- pressing the restore button on Firefox's default about:home home page.

Browsing history must be saved
- Firefox button: Firefox button > Options > Options > Privacy > [X] Remember my browsing history
- Menu Bar: Tools > Options > Privacy > [X] Remember my browsing history
Also make sure you do not clear "Browsing History" when using Clear Recent History or when closing Firefox
- Using Clear Recent History
- Firefox button: Firefox button > History >Clear Recent History
- Menu Bar: Tools > Clear Recent History
- When closing Firefox
- Firefox button: Firefox button > Options > Options > Privacy (checked) > Settings

To display the "Save Tabs and Exit" message when closing multiple tabs, you can do the following:
- Type about:config in the URL/Location/Address bar and press the Enter key
- Accept the warning message (promise to be careful)
- The preferences page/list will open
- Filter = browser.tabs.warnOnClose
- If its value is set to false, double-click on it (in the lower panel) to toggle its value to true
- Repeat steps 4 and 5 for these following 3 preferences also:
- browser.warnOnQuit
- browser.warnOnRestart
- browser.showQuitWarning
- Note: last pref is new in Firefox 4b12, may need to add (boolean)

I'm sure you are using Private Browsing mode in Firefox 4. I have also the same problem and I tried to uncheck this option after many times accessing about:config\browser.warnOnquit. And it's wonderful, the warning cameback. I think it's a bug about Private Browsing mode. Hope Mozilla's Developers will fix it.
