I've been using this, but it seems to break any sites that use facebook login, so it's pretty annoying to have to disable the extension whenever I need to login to a site that only has facebook login.
Facebook Container dev here. It breaks those sites because the extension blocks all Facebook resources (and tracking) from loading on non-Facebook sites.
To use Facebook login on a site, you'll need to add the website to the Facebook Container. Follow the directions from the docs[1]. This will stop you from having to turn the extension on and off entirely.
