New description:

 The Storage API (https://developer.mozilla.org/en-
 US/docs/Web/API/Storage_API) is the API that
 {{{
 defines a common, shared storage system to be used by all APIs and
 technologies that store content-accessible data for individual Web sites.
 The Storage API gives sites' code the ability to find out how much space
 they can use, how much they are already using, and even control whether or
 not they need to be alerted before the user agent disposes of site data in
 order to make room for other things.
 }}}
 We should think about neutering its fingerprinting/linkability potential.
 For now it seems it is disabled by `dom.storageManager.enabled` set to
 `false`. Moving to ff59-esr.

Comment:

 `dom.storageManager.enabled` is still set to false by default. I confirmed
 that there is no navigator.storage object in our alpha. Moving to
 ff59-esr.
