Facebook now offers frictionless sharing through their partner sites. In simple terms, if you are reading an article on a partner site, the service might share that article without requiring any action on your part.
If this was not annoying enough, your contacts were not able to directly click on that link to reach the article. Instead they were asked to approve the app for similar sharing on their own streams.
Frictionless is a new Google Chrome app that tries to fix it. It would bypass the app installation page and send you directly to the article page.
It is an open source project hosted on GitHub. They are looking for feedback on this extension. If you notice that this app is not able to parse a link correctly on Facebook, they want to know about it so that they can fix that thing too.
