Facebook has been long looking to convince the FB users to within its confines by providing all sorts of value added services like chats, messengers etc. However it lacked a full fledged browser that could take on the might of the market leader, Google Chrome and make its users stay on FB even while surfing the web. The new in-App browser is a step in making that into a reality. Besides the aesthetic shift, a new bar on the bottom tells you how popular a post is, includes back and forward buttons, lets you bookmark pages, and has a menu button which likely includes a few more features too. The only feature that is missing in the forthcoming Facebook browser is tab support. Apart from that the in-App browser is quite close to approximating a full-fledged app. Facebook hopes that once it gets the browser right, the Facebook app could essentially become a self-contained ecosystem of its own, it added. Right now the browser is only made available to a small subset of users (iOS only), but most public test features end up receiving a wider roll-out a few months later.
