At the moment, when you tap on a timeline link within the app, Facebook will load it in your default browser. This is not a pretty seamless solution, as users are forced to switch between the two apps. When you click on the link, the built-in Facebook browser apparently offers a limited, yet sufficient set of rather basic features (back, forward, copy address, open with, save, etc.), which are all accessible from a dropdown menu. The browser feature can be turned on or off from the settings of the app.
This feature has arrived with the latest update for a certain amount of users. It is rather unclear if it will be implemented for all users of the app at some point, or the built-in browser will remain just a brief experiment. We are slightly inclined towards the former possibility, as users of Facebook and the social network itself will most probably only benefit from such a seamless experience.
Are you rooting for such a functionality? Feel free to share your thoughts!
