I played a bit with localStorage in Firefox and it’s really useful to save data in the user’s browser without having to use cookies.
By now I tryed just a simple thing like saving your last visit in dallangelo.com home page and it looks to work! :)
I don’t know the space limit you can use, but as localStorage definition implies there will be more room than cookies :)
For reference -> DOM Storage
A reminder … to clear localStorage you can do localStorage.clear() in firebug :)
