A while back, Facebook introduced a feature where posts would pop up in your browser window if people respond to you. Now, I can certainly see how it is a useful feature to have, both for Facebook – it increases engagement with posts – and for users – you don’t have to leave the news feed to continue interacting. That said, I don’t like it. I would rather leave the news feed and go into a specific post if I want to follow up.
Luckily, the feature can be turned off, though if you don’t know where to look, it is a bit of a bear to find. To disable it, simply look to the bottom of the contacts list on the right-hand side, where you’ll find a gear. Click that, then click “Turn Off Post Tabs”:
