If you have been using Firefox 4 beta (12) recently, you may have noticed that Firefox does not save opened tabs and opens the browser with a fresh state. This behavior continues even if you have set the option “Show my windows and tabs from last time” under Tools>>Options>>General. Well don’t know whether its by design or bug, but Firefox wants you to set lot many other options manually before you get the old behavior back.
To achieve so, type ‘about:config’ in the address bar. Accept the warning message that appears, you will be taken to a list of preferences. Now locate the following preferences and set them to true if they are not by double clicking on the preference.
- browser.showQuitWarning [This option is to be set only for beta versions starting from 12]
And now you will observe, that old behavior is back. Well so much for the usability. Hoping that by the 4.0 final version, Firefox makes it more easy than to change 4 preferences manually like this.
