for( var i = localStorage.length - 1; i >= 0; --i ){
     var key = localStorage.key(i);
     console.log( key + ": " + localStorage.getItem(key) );
  }

    localStorage.key(Math.random()*localStorage.length)

It's pretty primitive, you have to go into the DOM tab for `window` and scroll down to `localStorage`.

Same for `globalStorage`.
