Liferay.on event not firing in Firefox

[John Leonard，修改在13 年前。]

Firefox doesn't seem to be firing my Liferay.on event. In my theme/_diffs/js/main.js, I've got

Liferay.on(
    'allPortletsReady',
    /*
    This function gets loaded when everything, including the portlets, is on
    the page.
    */

    function() {
        alert("loaded all portlets");
    }
);

And it works as expected in Chrome and Safari but never in FF.
