In figure 13.13, we see a permission denied error caused by the XMLHttpRequest object. There are two ways to correct this. The first is to go into the configuration file of Mozilla and set the permission setting to allow the XMLHttpRequest object to perform its desired task. To do this, we type about:config into the address bar of the browser and adjust the setting, but that is not a safe procedure to perform. The reason it is not safe is that we are enabling it for anything that runs on our computer. That means any script that wants to talk to the outside world would be able to do so. How can we avoid this and allow only our Ajax application to talk to the outside The solution is to set the security with JavaScript.
