Awhile backhow to unfollow a comment thread or post on Facebook. The process wasn't all that straightforward and required you know where to click, and what to look for once you did.
Recently, Facebook gave its notification box a revamped look, as well as a new feature. You can now unfollow a post directly from the notification box.
As you can see above, in the top-right corner of each notification you'll see a small X. When the X is clicked on, you'll be asked to confirm that you do want to unfollow that post. After confirming, the notification will disappear, being replaced with an undo button (should you change your mind). Going forward, you'll no longer receive alerts from the status update you just unsubscribed from.
According to Lifehacker, the feature will roll out to everyone over the course of the day, with app controls coming in the "near future."
