UPDATE March 28: On a Related Note: It’s Time to Make Our (Facebook) Privacy Tools Easier to Find (via Facebook Newsroom) & Facebook Introduces Central Page for Privacy and Security Settings (via NY Times)
As a user of the internet, you deserve a voice and should be able to use the internet on your own terms. In light of recent news on how the aggregation of user data can be used in surprising ways, we’ve created an add-on for Firefox called Facebook Container, based on technology we’ve been working on for the last couple of years and accelerated in response to what we see in terms of growing demand for tools that help manage privacy and security.
Facebook Container isolates your Facebook identity from the rest of your web activity. When you install it, you will continue to be able to use Facebook normally. Facebook can continue to deliver their service to you and send you advertising. The difference is that it will be much harder for Facebook to use your activity collected off Facebook to send you ads and other targeted messages.
[Our emphasis] Facebook isn’t unique in their practice of collecting data from your activity outside of the core service, and our goal is not to single out a particular organization, but to start with a well-defined problem that we can solve quickly.
