Makes Facebook permissions optional.
Have you ever wanted to disallow specific permissions from apps who use your Facebook account, but still be able to login? This extension is for you.
Why do some sites break when using this plugin?
Sometimes server-side code is written without the consideration that a Facebook permission might not have been granted. They might get a permission denied back from Facebook and not handle it gracefully. Some sites might be more aggressive than others about checking which permissions you're missing and trying to get you to re-auth.
