One change in Firefox 4 is to by default stop Firefox displaying the warning message, but it can be turned back on by changing some preferences.

  1. Type about:config into the location bar and press enter
  2. Accept the warning message that appears, you will be taken to a list of preferences
  3. Locate the preference browser.tabs.warnOnClose, if its value is set to false, double-click on it to change its value to true
  4. Repeat this for these 3 preferences browser.warnOnQuit, browser.warnOnRestart and browser.showQuitWarning

If you always open the last set of tabs, an alternative approach is this:

  1. Click the orange Firefox button, then select options to open the options window
  2. Go to the General panel
  3. Change the setting "When Firefox starts" to "Show my windows and tabs from last time"
