Are you targeting ES5? If so it's probably the problem described in #4031

EDIT: Actually #3164 describes the problem, and #4031 is a response to that

It seems FileList does not support iterator yet, so it won't work even on ES6 mode as of now.

[Exposed=Window,Worker] interface FileList {
  getter File? item(unsigned long index);
  readonly attribute unsigned long length;
};
