<preferences> is a container for <preference> elements. It's supposed to be a child of <prefpane> element.

<preferences> element should contain one or more <preference> elements.

Note: it's not clear which of the following methods and properties are public.


  <preference id="pref_one" name="extensions.myextension.one" type="bool"/>
  <preference id="pref_two" name="extensions.myextension.two" type="string"/>
    ... etc ...


These ought to be readonly; three of these could be merged into a single member

attribute nsIPrefService service; 
The preferences service.
attribute nsIPrefBranch rootBranch; 
The root prefs branch.
attribute nsIPrefBranch defaultBranch; 
The root branch of the tree with default values.
attribute nsIPrefBranch2 rootBranchInternal; 
The root prefs branch (nsIPrefBranch2).
