Privacyfix is a brand new app for Mozilla Firefox and Google Chrome aimed to make your online activities private.
It has dedicated features for Facebook and Google enabling you to see how public your online activities are.
You also get the ability to change settings on these services to make your accounts more private.
It also has sections focused on tracking cookies. You can also enable a healthbar which shows the amount of tracking done by individual websites you visit.
The app also tries to guesstimate how much you are worth for Facebook and Google based on your online activities!
