Earlier quoted context omitted.
I used this for a while but noticed it greatly slowed down my Facebook in general. Ended up uninstalling it after a few days. Wish they had a lighter weight one.
I know this might sound like a really non-efficient thing to do, but you can individually unfollow every single one of your contacts. I only have around ~200 friends so unfollowing them wasn't that hard. Nowadays, I love going to Facebook. My news feed is completely empty.
I've probably only unfollowed about 10% of my total friends list, but the difference is immense, a lot of the noise tends to come from a small subset of the people, in my experience.
