I just created a useful tool to help you get the facebook ID. This is really the simplest way to do it, you don’t need to know how to use javascript or even firebug add-on , all you need to do is simply put any facebook profile url inside the textbox below then press the “Find The ID” button.

You can even use this to find out about your fan page id . we will discuss about how to find facebook group id later on another post. Here’s the tool :
