According to reports Facebook is testing its own built-in Web browser for the Android app. Several users reported app opening external links from their timeline and news feeds in its own built-in browser window after the recent Facebook for Android update.
Android Police says that the built-in browser seen by users is a WebView component based on the Chromium open source project. The app uses a WebKit rendering engine to display webpages and does simple actions including back, forward, zoom, and search functions. Some users have shared the screenshots of the built-in Facebook browser which shows a menu button on the top right corner with forward and back buttons, an option to Share in New Post, Open with, Copy link, and Save links.
Facebook's thinking behind the browser is simple, the more time users spend on the app means more ad revenue for the social networking site. Facebook has not issued any official statement on the feature and it remains to be seen whether it will be rolled-out to all users or is just another one of the company's experiments.
Facebook has recently confirmed that it is testing the option to post stickers in comments on its site. Few users have been using the stickers in comments section for testing, though the company has not issued any official statement about a global rollout. The social networking site is also testing 'Satire' tags after it received feedback that people wanted a clearer way to distinguish between fake and real news articles.
