First things first  you need to check to make sure that localStorage is enabled  I would recommend doing it like this   var localStorageEnabled   false  try   localStorageEnabled     localStorage    catch e        Yes  you can  in some cases  just check to see if the localStorage is a member of the window object  However  there are iframe sandboxing options  among other things  that will throw an exception if you even attempt to access the index  localStorage   Thus  for best-practices reasons  this is the best way to check to see if the localStorage is enabled  Then  you can just clear the localStorage like so   if  localStorageEnabled  localStorage clear      For example  you could clear the localStorage after an error occurs in webkit browsers like so      clears the local storage upon error if  localStorageEnabled    window onerror   localStorage clear bind localStorage     In the above example  you need the  bind window  because without it  the localStorage clear function will run in the context of the window object  instead of the localStorage object making it silently fail  To demonstrate this  look at the below example   window onerror   localStorage clear    is the same as   window onerror   function        localStorage clear call window
