I have added the Topicala (www.topicala.com/) application in to Facebook (www.facebook.com).
If you add this application you will be able to search the Internet with directly leaving Facebook.
The application can be found at http://apps.facebook.com/topicala/
The application was really simple to develop and doesn't require that you pass any personal details to Topicala.
Let me know what you think. I appreciate all feedback.
I lead the Chrome Developer Relations team at Google.
We want people to have the best experience possible on the web without having to install a native app or produce content in a walled garden.
Our team tries to make it easier for developers to build on the web by supporting every Chrome release, creating great content to support developers on web.dev, contributing to MDN, helping to improve browser compatibility, and some of the best developer tools like Lighthouse, Workbox, Squoosh to name just a few.
