            Bug ID: 207545
           Summary: Blocking Access to LocalStorage and SessionStorage for
                    specific web-sites or for all websites doesn't work
                    100% of the time
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iPhone / iPad
                OS: All
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: WebKit API

In order to block LocalStorage access or SessionStorage, developers need to inject some Javascript like like:
```
var localStorage = Object.getOwnPropertyDescriptor(window, 'localStorage');
if (localStorage) {
    Object.defineProperty(window, 'localStorage', {
        get: function() {
            console.error("Local Storage Blocked")
            return null;
        },
    });
}

var sessionStorage = Object.getOwnPropertyDescriptor(window, 'sessionStorage');
if (sessionStorage) {
    Object.defineProperty(window, 'sessionStorage', {
        get: function() {
            console.error("Session Storage Blocked")
            return null;
        },
    });
}
```

There should be a simpler way to deny a website or anything access to the storage. Currently, there is none.
