Orbitum is a new browser that focuses on integrating with social networks. Orbitum is simple, easy to use and makes it very easy to access social networking sites such as Facebook and Twitter without actually having to log into any of them. Integration with Facebook is significantly better than other sites however. Orbitum allows you to log into Facebook chat directly and also allows you to filter who you appear online to. Orbitum also includes a few useful security features. Orbitum alerts you if you're about to access a potentially malicious site although this is nothing particularly special - most modern browsers such as Firefox and Chrome have anti-phishing detection integrated.
