[1] Nightly of Gecko 24 got an experimental implementation of PromiseResolver, under the initial name of FutureResolver. It got renamed to its final name in the Gecko 25. To disable it, the preference dom.promise.enabled (in Gecko 24, dom.future.enabled) must be switched to false. Note, only Nightly and Dev Edition versions of Firefox get this interface enabled by default. Beta and Release versions of Gecko have them disabled by default.
