(See nsIContentPref below.) + * + * For example, if you want to remember the user's preference for a certain zoom + * level on www.mozilla.org pages, you might store a preference whose domain is + * "www.mozilla.org", whose name is "zoomLevel", and whose value is the numeric + * zoom level. + * + * A preference need not have a domain, and in that case the preference is + * called a "global" preference.

As a consumer of this + * interface, you might choose to let a global preference override all non- + * global preferences of the same name, for example, for whatever definition of + * "override" is appropriate for your use case. + * + * + * Domain Parameters + * + * Many methods of this interface accept a "domain" parameter. Domains may be + * specified either exactly, like "example.com", or as full URLs, like + * "http://example.com/foo/bar". In the latter case the API extracts the full + * domain from the URL, so if you specify "http://foo.bar.example.com/baz", the + * domain is taken to be "foo.bar.example.com", not "example.com". + * + * + * Private-Browsing Context Parameters + * + * Many methods also accept a "context" parameter. This parameter relates to + * private browsing and determines the kind of storage that a method uses, + * either the usual permanent storage or temporary storage set aside for private + * browsing sessions. + * + * Pass null to unconditionally use permanent storage. Pass an nsILoadContext + * to use storage appropriate to the context's usePrivateBrowsing attribute: if + * usePrivateBrowsing is true, temporary private-browsing storage is used, and + * otherwise permanent storage is used.
