It works wunders on my browser, but it doesn't work when i use it on my android phone, through firefow nightly :(

Used to work like a charm! Stopped working a few days ago because of facebook changes.

Does hide the feed, but along the way hides "close" button in chats too (new Facebook UI)

This worked great until the latest update.

Now it's not only blocking the News Feed — if you try to view an individual post on Facebook (e.g. https://www.facebook.com/username/posts/8852821772405) it just doesn't show up.

Doesn't seem to work in Firefox 58
