Get ready, Firefox browser with Australis design is coming soon with version 29 to stable channel, currently in the Beta. It’s easy to ignore about Menu -which you don’t use much except for opening new private window, add-ons Manager and options – looks similar to that of Chrome’s which lacks customization option but not this one, Australis powered Mozilla browser offers customization mode (accessible from the Menu), lets you move unnecessary menu items you don’t use too often from the menu to Additional tools and features or to the toolbar. You can also move Add-on icons (remember, add-on bar has been removed) on the toolbar to Menu.
