window.external.IsSearchProviderInstalled and window.external.AddSearchProvider will both be defined as methods that are no-ops. This was never implemented in Safari. In IE10, these methods are (mostly) no-ops: IsSearchProviderInstalled always returns 2, and AddSearchProvider always returns S_OK. Firefox still implements this, but notes that it may be removed at any time.
