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
`true`. We should verify that for ESR52, though.
