Firefox users are probably already aware of how the browser boasts itself as a more secure application than Internet Explorer, however you can make it even more secure by utilizing the NoScript plugin.

NoScript basically disables JavaScript, Java, Flash and other possible exploit laden vehicles for non-trusted sites. This ensures browser execution from unknown or unauthorized sites is not a concern on your machine. Additionally, you can easily set NoScript to allow execution on trusted sites so your browsing experience is uninterrupted.

As their tag line states:

There’s a browser safer than Firefox…
…it is Firefox, with NoScript!
