Get Firefox 4 to Ask You to Save Tabs on Exit

One weird thing I noticed when I upgraded to Firefox 4 is that you no longer get offered the option of saving your tabs on exit.

This often came in handy for me at times when I needed to restart the browser for what ever reason (plug-in install, computer restart, etc) so I do wonder why it is disabled by default on Firefox 4.
Perhaps it is not used as often as I thought it might be…

Anyway, you can easily re-enable this prompt by following the simple steps below:

  1. In the URL bar, type about:config
  2. Search for the following and set them all to true (you can do this by either double clicking the value or right clicking –> Toggle)

browser.tabs.warnOnClose
browser.warnOnQuit
browser.warnOnRestart
browser.showQuitWarning

You should now be prompted to save your tabs when you exit Firefox (as long as you have two or more tabs open of course ;))

Update: This should also work on Firefox 5.

INSERT INTO LocalStock

VALUES (1000, True, 10.20, 17.5)

    This information helped me out tremendously!! Thank you so much. I just upgraded my firefox and it took away the ability to save my tabs. Thanks again for showing me how to get the tabs to stay even after I exit Firefox.
