Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.<br /> You can use "Firefox > History > Restore Previous Session" to get the previous session.<br /> There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.<br /> Another possibility is to use:<br /> *Firefox (Tools) > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time" You can set the warn prefs on the <b>about:config</b> page to <b>true</b> via the right-click context menu or toggle the value with a double left-click. * browser.showQuitWarning, see http://blog.zpao.com/post/3174360617/about-that-quit-dialog * browser.tabs.warnOnClose, see http://kb.mozillazine.org/About%3Aconfig_entries * browser.warnOnQuit , see http://kb.mozillazine.org/browser.warnOnQuit * browser.warnOnRestart , see http://kb.mozillazine.org/browser.warnOnRestart To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br /> If you see a warning then you can confirm that you want to access that page.<br />
