//Local storage only stores string
//so if you do this in one browser.....

var obj = {'name':'rick', age:100};

localStorage['empId1'] = obj;


//Then this in the other browner (same URL)...

var obj = localStorage['empId1']

//obj is this string... "[object Object]"

//This is not actual very useful.

//Instead you need to do this


//In the first browser do this.
localStorage['empId1'] = SC.json.encode(obj);
// which stores this string "{"name":"rick","age":100}"

//Then retrieve it as follows in the other browser:
var obj = SC.json.decode(localStorage['empId1']);

// now obj.name is "rick"
