Pixel Activated Multiple Times for Facebook Pixel

问题:

I am using some Javascript I got from Facebook to execute a "tracking" pixel. But when I use the "Facebook Pixel Helper" to see if things are working correctly, it indicates there is an error, and the pixel is being activated multiple times. It gives no instructions on how to resolve such an error, or even where to look. Are there changes I can make in this code from Facebook that would prevent this multiple firing?

 <script>
    (function() {
        var _fbq = window._fbq || (window._fbq = []);
        if (!_fbq.loaded) {
            var fbds = document.createElement('script');
            fbds.async = true;
            fbds.src = '//connect.facebook.net/en_US/fbds.js';
            var s = document.getElementsByTagName('script')[0];
            s.parentNode.insertBefore(fbds, s);
            _fbq.loaded = true;
        }
        _fbq.push(['addPixelId', '368842449990820']);
    })();

    window._fbq = window._fbq || [];
    window._fbq.push(['track', 'PixelInitialized', {}]);
</script>

There was a bug in the "Facebook Pixel Helper" extension that sometimes led to this error. They updated it today so you may be able to fix the error simply by updating to the latest version of the extension.
