localStorage 不适用于 Ubuntu Canconical 1.0 的 Mozilla Firefox 22.0

Question

我有一个网页，上面有两张表格。按钮位于它们下方。当我单击按钮时，我使用淡入/淡出切换表单显示/隐藏。我添加了该功能，这样即使我刷新页面，第一个是当前表单的表单仍然是当前表单。为此，我使用了 html5 localStorage。我在 Chrome 中运行良好，但在 Mozilla Firefox 22.0 for Ubuntu Canconical 1.0 中无法运行。

HTML：

<section id="content">
    <div id="logo" style="margin-left: 0;"></div>
    <div id="container">
        <form id="sign_up" action="login.php" method="post">
            <table style="margin: 0px auto;">
                <tr>
                    <td align="center"> <span style="font-weight: bold;font-size: 2em; color: Gray;">Sign Up</span>

                    </td>
                </tr>

    </div>
</section>

CSS：

#content {
    margin-top: 10%;
}
#container {
    margin: 0 auto;
    width: 80%;
    text-align: center;
}
input[type=text], input[type=password] {
    width: 250px;
    min-height: 25px;
    border-radius: 3px;
    border: 0;
    padding: 7px;
    font-family: Calibri;
    font-size: 20px;
    box-shadow: 0px 0px 3px 1px #aaa inset;
    box-sizing: border-box;
}
#sign_in, #sign_up {
    border: 1px solid #4f4f4f;
    border-radius: 10px;
    margin: 0 auto;
    max-height: 250px;
    width: 292px;
    padding: 10px;
    background-color: #eee;
    border: 0px;
    box-shadow: 0px 0px 15px 1px #000;
}
#sign_up {
    display: none;
    max-height: 275px;
}

JS：

jQuery(function ($) {

    var $sUp = $("#sign_up"),
        $sIn = $("#sign_in");

    $("#content").on('click', "#sign_up_btn", function () {

        $sIn.stop().fadeOut(800, function () {
            $sUp.fadeIn(800);
        });
        $(this).stop().fadeOut(800, function () {
            $(this).attr({
                value: "Already have an account?",
                id: "sign_in_btn"
            }).fadeIn(800);
        });
        localStorage.setItem('lastForm', 'sign_up');
    }).on('click', "#sign_in_btn", function () {

        $sUp.stop().fadeOut(800, function () {
            $sIn.fadeIn(800);
        });
        $(this).stop().fadeOut(800, function () {
            $(this).attr({
                value: "Create An Account",
                id: "sign_up_btn"
            }).fadeIn(800);
        });
        localStorage.setItem('lastForm', 'sign_in');
    });

    if (localStorage.getItem('lastForm') == "sign_up") {
        $sIn.fadeOut(0);
        $sUp.fadeIn(0);
    }
});

如何使cross-browser 兼容？

试试这个：

localstorage.lastform="sign_in";
