问题 I have view a that has a table cell and a save button. If I touch the table cell, a new navigation view slides in ( view b ). In the view b, I have one UITextView where I type all the context I need save. And of course there is 'back' button on the top left side of the 'view b'.

问题 Let me start off by saying I am new to add-on development. Using the Add-on SDK, I am trying to create a simple Firefox add-on that, when a button is pressed, acts like pressing the Ctrl-S hotkey, or following the file -> save page as to get the save page pop up window.
