Try good Extensions to your firefox !!!

What is extension in firefox?

Extensions are small add-ons that add new functionality to Mozilla applications. They can add anything from a toolbar button to a completely new feature. They allow the application to be customized to fit the personal needs of each user if they need additional features, while minimizing the size of the application itself.
