Hi. If you try to open this HTML page in Firefox 3.6.8, Firefox is 1000 times slower than IE 8,Opera 10 and Chrome. I cannot believe that localStorage.setItem is so slow in Firefox. Is there a solution ? Thanks in advance

<title>Storage test</title> <script type="text/javascript"> var TestValue = "1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890"; for (var i = 0; i < 1000; i++) { localStorage.setItem(i, TestValue); } </script>
