Social media giant Facebook is reportedly testing out a new feature that pushes posts as a pop-up similar to the chat window at the bottom of the screen. “People said that they would like an easier way to participate in conversations on a particular post while they are still in New Feed. So we are testing a new option that opens up a window when someone comments, replies or tags you in a post” said Facebook spokeswoman. Facebook is reportedly introducing this option to improve News Feed experience.
