Mission Accomplished
In this project we've covered most of the basics of building a Chrome extension. We covered creating a browser action that triggers a popup when it is clicked in order to display saved contacts.
We also saw how we can safely sandbox pages that need to run dangerous code such as eval() or new Function in order to protect our extension from XSS attacks, and how we can use the simple messaging API to send messages and receive responses to an <iframe> element containing the sandboxed page.
