The NativeWindow object is only available to privileged code running on Firefox for Android, and is intended for use by Firefox for Android add-ons.
Summary
NativeWindow.contextmenus.add() adds an item to the context menu in Firefox for Android, returning an ID for the item. To remove the item, use NativeWindow.contextmenus.remove(), passing in the item's ID.

var menuID;
function loadIntoWindow(window) {
if (!window)
return;
let label = "Show HTML";
let selector = window.NativeWindow.contextmenus.SelectorContext("*");
menuID = window.NativeWindow.contextmenus.add(label, selector, function(target) {
window.NativeWindow.toast.show(target.outerHTML, "short");
});
}
function unloadFromWindow(window) {
if (!window)
return;
window.NativeWindow.contextmenus.remove(menuID);
}
