[1] Firefox 51 introduced NavigatorStorage, navigator.storage, and the StorageManager.estimate() method. These are enabled by default in nightly builds but disabled by default in all other builds. You can enable these features by setting the preference dom.storageManager.enabled to true.
[2] Firefox 55 introduced StorageManager.persist() and StorageManager.persisted() methods. Users can also manage persistent-storage data in Preferences "Privacy and Security" -> "Site data". These are enabled by default in nightly builds but disabled by default in all other builds. You can enable these features by setting the preference dom.storageManager.enabled and browser.storageManager.enabled to true.
