Hello, exactly the same problem here, it started about 24 hours ago. Like DavidGB I just can't do anything on the whole Rendero website, trying to check new products, or galleries, will just freeze Firefox, with an error message about ajax script from googleapis (it's not a simple long wait or connection time out, it's literally freezing/locking the browser process itself). I'm using another browser right now, just to come post this.

A screencap just in case it can help :
