Cocoon yourself for safety

I thought I would mention a useful looking piece of software called Cocoon. Its a safety oriented Firefox browser add-on and its free.
The developers describe it as
Cocoon protects your identity so your data trail leads nowhere. Now you can enjoy the  Web knowing you are safe from prying eyes. Cocoon stops companies from tracking  your movements and collecting your data online. The Cocoon Servers protect your  computer whenever you go online. Viruses, spyware and malicious software can’t touch you. Cocoon lives in the cloud, so you can access your history, bookmarks and security settings from any computer, anytime.

You will need to supply your email address and when the email authorisation comes through sign up to get an account. You will then need to launch firefox and get the add-on installed
