MDN wants to talk to developers like you:


An object of type bookmarks.BookmarkTreeNode represents a node in the bookmark tree, where each node is a bookmark or bookmark folder. Child nodes are ordered by an index within their respective parent folders.


An object with the following properties:

A string which uniquely identifies the node. Each ID is unique within the user's profile and remains unchanged across browser restarts.
parentId Optional
A string which specifies the ID of the parent folder. This property is not present in the root node.
index Optional
A number which represents the zero-based position of this node within its parent folder, where zero represents the first entry.
url Optional
A string which represents the URL for the bookmark. If the node represents a folder, this property is omitted.
A string which contains the text displayed for the node in menus and lists of bookmarks.
dateAdded Optional
A number representing the creation date of the node in milliseconds since the epoch.
dateGroupModified Optional
A number representing the date and time the contents of this folder last changed, in milliseconds since the epoch.
unmodifiable Optional
A string as described by the type bookmarks.BookmarkTreeNodeUnmodifiable. Represents the reason that the node can't be changed. If the node can be changed, this is omitted.
children Optional
An array of bookmarks.BookmarkTreeNode objects which represent the node's children. The list is ordered in the list in which the children appear in the user interface. This field is omitted if the node isn't a folder.

At this time, this object doesn't have a way to describe a separator within a bookmark list.
