Problem :
Webdriver will just initiate the browser, prompting for a search or address and that ends there with an exception:
org.openqa.selenium.firefox.NotConnectedException:
What is Selenium?
Selenium is a Suite (group) of tools i.e., Selenium IDE, Selenium WebDriver and Selenium Grid to automate web browsers across many platforms.
What is Selenium IDE, WebDriver, and Grid?
Selenium IDE: It is a Firefox plugin which is used to Record and Play the Test Scripts.
Selenium WebDriver: It is a tool which provides an API (that can be understood easily) to automate web browsers with the help of programming languages like Java, Csharp, Python, PHP, Perl, Ruby, and JavaScript.
Selenium Grid: It transparently distributes tests into Remote machines. That is, running multiple tests at the same time against different machines running different browsers and operating systems.
What are the locators available in WebDriver?

What is Selenium Grid?
Selenium Grid is a tool used together with Selenium RC to run parallel tests across different machines and different browsers all at the same time. Parallel execution means running multiple tests at once.
Features:
Enables simultaneous running of tests in multiple browsers and environments.
Saves time enormously.
Utilizes the hub-and-nodes concept. The hub acts as a central source of Selenium commands to each node connected to it.
