If anyone has ever used In Firefox 3, you will see button “Save and Quit” when exit Firefox. This feature which allow users to save all current open tabs before closing Firefox is very helpful. And of course, all of you surely like this function, I think.
But in Firefox 4 through 10, this feature does not appear by default.
When closing Firefox(currently I am using version 10), it displays as the below image.
In order to enable this feature, do the following step by step :
- 1. In Firefox, at the URL address box, type in “about:config” and press “Enter” to go, then click on “I’ll be careful, I promise!“.
- 2. Because Firefox 10 supports auocomplete in “Filter” box, so you just need to type “quit“,it will auto filter for you.The item “browser.showQuitWarning” appears in the filter result, then double click on this item or right click on this item and choose “Toggle“
The value of “browser.showQuitWarning”is changed from “false” to “true”
The configuration finishes here, now we try to close Firefox and will see the expected result.
