In order to get your tabs and windows back from the previous session, you should close Firefox from the menu: At the top of the Firefox window, click on the Firefox button (File menu in Windows XP) and then click Exit. If you close each window or tab, only the final window or tab that you closed will be available when you restart Firefox.Prior versions of Firefox would ask “Do you want Firefox to save your tabs for the next time it starts?” when exiting the program. FF4 no longer has this feature enabled by default. Here is how to turn it back on.
Steps To Follow
- Open the configuration page by typing about:config in the address bar.
- In the configuration page search for browser.showQuitWarning in filter.
- The default value for this entry will be False, double click on it change to True.
- Restart Browser for effect to take place.
