Source: Configure Firefox To Only Open Whitelist Websites
The best way of controlling which websites are opened in a web browser is to block all of them except those that are listed on a custom whitelist. This does require work at the beginning when websites are added to the whitelist but reduces the level of control that has to be imposed on the user once the whitelist has been filled with domains. This can not only be practicable for companies or organizations who want to restrict Internet access to a handful of selected websites but also for parents who want to protect their children from the dangers of the Internet without giving them the feeling that they under total control.
ProCon Latte is an add-on for the Firefox web browser that can block access to all websites except those that are listed in the whitelist. While the add-on provides access to many additional features like word based filters this article concentrates on using it to block all websites except whitelisted ones. The options of the add-on contain a form that can be filled with whitelisted urls. It is also possible to import a list of urls that should be added to the whitelist or right-click the current page and select the option to whitelist it.
It would not be a very good protection if anyone would be able to add new pages to the whitelist. This is where the password protection of the application comes into play. Once password protected only authorized users - those that enter the password correctly - can make changes to the add-on's options. Several options are available to increase the security further by hiding the extension from the tools menu and status bar, preventing it from being disabled or uninstalled and by locking about:config so that it cannot be accessed.
