At variance with Firefox 3, Firefox 4 does not ask me to save the opened tabs when I quit on having multiple opened tabs. How can I do this in Firefox 4?

In Firefox 3, when I happened to close the program on having multiple opened tabs, Firefox asked me if I wanted to save and remember the opened tabs, so that I could retrieve them at the next Firefox restart. Firefox 4 does not do this anymore. Is it because I have not configured it correctly somehow, or is this normal? How can I recover this function? Thanks in advance, Andrea

Chosen solution

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
