+/**
+ * Quits the application with the provided flags.
+ *
+ * Optional {@link nsIAppStartup} flags may be provided as
+ * an array of masks, and these will be combined by ORing
+ * them with a bitmask. The available masks are defined in
+ * https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Reference/Interface/nsIAppStartup.
+ *
+ * Crucially, only one of the *Quit flags can be specified. The |eRestart|
+ * flag may be bit-wise combined with one of the *Quit flags to cause
+ * the application to restart after it quits.
+ *
+ * @param {Array.<string>=} flags
+ *     Constant name of masks to pass to |Services.startup.quit|.
+ *     If empty or undefined, |nsIAppStartup.eAttemptQuit| is used.
+ * @param {boolean=} safeMode
+ *     Optional flag to indicate that the application has to
+ *     be restarted in safe mode.
+ * @param {boolean=} isWindowless
+ *     Optional flag to indicate that the browser was started in windowless mode.
+ *
+ * @returns {Object<string,boolean>}
+ *     Dictionary containing information that explains the shutdown reason.
+ *     The value for `cause` contains the shutdown kind like "shutdown" or
+ *     "restart", while `forced` will indicate if it was a normal or forced
+ *     shutdown of the application. "in_app" is always set to indicate that
+ *     it is a shutdown triggered from within the application.
