Safari extension builder no "+" sign to add new extension folder I have an extension that I need to build back to safariextz, but there is no + sign to add new extension. In the tutorials there are + signs but they are old tutorials and there is no new information. How do I build extension?
In Safari, from the Develop menu, choose Show Extension Builder.


Choose Continue from the Xcode promotion sheet if shown.
From the bottom-left of the window, click the + button.
