为什么这个 jQuery AJAX PUT 可以在 Chrome 中工作，但不能在 FF 中工作

In Chrome this does an HTTP PUT just like it should, but in FireFox 21 it doesn't. There are no errors in the javascript console or in the backend.

这是 HTML:

<div id="createTeamModal" class="small reveal-modal">
        <form id="createTeamForm">
            <div class="row"><p id="teamFlavorText" class="lead">Building a new team</p></div>
            <div class="row">
                <div class="small-4 large-4 columns"><label>Team Name:</label></div>
                <div class="small-6 large-6 columns"><input name="teamName" id="teamName" type="text" size="20"/></div>
            </div>
            <div class="row"><p class="lead">Does this team work for a business?</p></div>
            <div class="row">
                <div class="small-4 large-4 columns"><label>Business Size:</label></div>
                <div class="small-6 large-6 columns">
                    <select id="businessSizeSelect" name="businessSizeSelect">
                    <option value="1">Nope, I work alone</option><option value="2">2 to 49</option><option value="3">50 to 99</option><option value="4">100 to 999</option><option value="5">1,000+</option>
                    </select>
                </div>
            </div>
            <div id="businessLocationDiv" class="row" style="display: none; margin-top: 20px;">
                <div class="small-4 large-4 columns"><label>Business Location:</label></div>
                <div class="small-6 large-6 columns">
                    <select id="businessLocationSelect" name="businessLocationSelect">
                    </select>
                </div>
            </div>
            <div id="businessTypeDiv" class="row" style="display: none; margin-top: 20px;">
                <div class="small-4 large-4 columns"><label>Industry:</label></div>
                <div class="small-6 large-6 columns">
                    <select id="businessTypeSelect" name="businessTypeSelect">                      
                    </select>
                </div>
            </div>
            <div class="row" style="margin-top: 20px;">
                <div class="large-offset-10 small-1 large-1 columns">
                    <button id="createTeamButton" class="small button">Create</button>
                </div>
            </div>
        </form>
        <a class="close-reveal-modal">&#215;</a>
    </div>

这里是 jQuery:

$("#createTeamButton").click(function () {
    var teamObject = new Team();
    teamObject.description = $("#teamName").val();
    teamObject.businessSize = $("#businessSizeSelect").val();
    teamObject.businessType = $("#businessTypeSelect").val();
    teamObject.businessLocation = $("#businessLocationSelect").val();

    $.ajax({
        type: "PUT",
        url: "/ajax/rest/team",
        dataType: "json",
        data: JSON.stringify(teamObject),
        success: function () {
            // Reload the team select box
            loadTeamSelectBox();

            // Pop up the site create modal
            $('#createSiteModal').foundation('reveal', 'open');
        },
        error: ajaxErrorHandler
    });
});
