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 unless you are in Private Browsing mode. You can restore them next time by:
    1. clicking Firefox button > History >"Restore Previous Session", or
    2. type about:home in the URL bar and press the Enter key, then press the "Restore Previous Session" button
    3. See: https://support.mozilla.com/en-US/kb/Firefox%20does%20not%20ask%20to%20save%20tabs%20and%20windows%20on%20exit
  • Note: This was a decision by the developers. On this forum, we are all uncompensated volunteers here to help other users. The developes/employees of Mozilla/Firefox rarely, if ever visit here.

To display the "Save Tabs and Exit" message when closing multiple tabs, you can do the following:

  1. Type about:config in the URL/Location/Address bar and press the Enter key
  2. Accept the warning message (promise to be careful)
  3. The preferences page/list will open
  4. Filter = browser.tabs.warnOnClose
  5. If its value is set to false, double-click on it (in the lower panel) to toggle its value to true
  6. Repeat steps 4 and 5 for these following 3 preferences also:
    • browser.warnOnQuit
    • browser.warnOnRestart
    • browser.showQuitWarning
  7. See:

Some things to check if tabs are not being saved:

  1. 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
  2. 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
  3. Make sure you are not in Private Browsing mode or in permanent Private Browsing mode:
  4. If you have theTab Mix Plus extension, then disable the built-in session restore.
