Sometimes, software applications look like a computer game because they hide menus, options or features. The way computer games have secrets or cheats, the same way some applications encapsulate hidden resources that in a normal procedure are not revealed for the user. It's like having a car and not knowing what's under the hood. Did you know that your web browser has something to hide from you? I bet you didn't.

Mozilla Firefox is a dangerous competitor for the almost omnipresent Internet Explorer. Constantly improved over the last years, it has become a reliable alternative for the Microsoft's product.
