A few months ago, I got to work on the designs for blocking embedded content from Facebook. This can be embedded videos, comments, posts, pages, groups, and login buttons on the websites that you visit.
This is greatly limits what Facebook can learn from you as you browse the web, and it’s also convenient to unblock if you’d like to view the content. Here’s what it looks like:
The login flow is a little different. We prominently show you that the login button is blocked, and we also tell you about our limitations when you do log in with Facebook.

It took a lot of user testing and even more design variations, but we ultimately landed on simple, unobtrusive messages so that it gets out of the way of what people are doing. Super happy about this—I hope you can try it out yourself using the extension!
