     <h3>Hello and Welcome</h3>

    <p>The event exists within Chrome but not within Firefox and without calling event.stopPropagation, other parts of our code cannot function.</p>
</textarea>

JavaScript

$(function () {

    // Init redactor
    $('#redactor').redactor({
    });    

    var that = $('#redactor').data('redactor');
   
    that.buttonAddFirst('mailmerge', 'Merge Fields', function (name, $button, button_obj) {
        var btn = that.buttonGet('mailmerge');

        alert("event: " + window.event);
        if (window.event !== undefined && window.event !== null)
            window.event.stopPropagation();
    });
});
