This is a bookmarklet that will dump the HTML5 localStorage object into a bookmarklet that you can then import into another browser.

javascript:(function(){
var key; 
var undump = ""; 
for (var i = 0, len = localStorage.length; i < len; i++){ 
key = localStorage.key(i); 
undump += "localStorage.setItem('" + key + "','" + localStorage.getItem(key) + "'); "; } 
console.log(undump);
window.prompt("Bookmarklet", "javascript:(function(){ localStorage.clear(); " + undump + "}());" );  
}());
