Answer 1

Just type localStorage in your console, you will get all the data stored in local storage. Since it is a json type dictionary, you can simply iterate through all the elements like this:

local = localStorage;
for (var key in local) {
  console.log(key);
//Do something with key, access value by local[key]
}

This will give you all the keys in dict in console.
