If you’ve recently updated to Firefox 4, then you must have noticed a new design and some new features. But there’s one very handy feature ‘Save and Exit’ which is missing in Firefox 4, but was available in previous versions of Firefox browser. However, there is a quick and easy way to get back this option, which restores all the tabs opened in the browser on re-opening Firefox 4.
To Enable ‘Save and Quit’ feature in Firefox 4, just type
about:config in the address bar and open it. Enter
browser.showQuitWarning in the Filter tab. Double-click the entry named browser.showQuitWarning so that its value changes to ‘true’. That’s it!
Now you’ll be presented with ‘Quit Firefox’ dialog box on closing Firefox 4. 🙂
Thanks @rish404 for the tip.
