Facebook can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a profile revealing information about themselves. They can post text, photos and multimedia which are shared with any other users who have agreed to be their “friend” or, with different privacy settings, publicly. Users can also communicate directly with each other with Facebook Messenger, join common-interest groups, and receive notifications on the activities of their Facebook friends and the pages they follow.

On February 24, 2016, Facebook released a set of “reactions” (called Reactions) alongside the familiar “Like” button. Now, users can express different attitudes with this set of emotions, which are: “Favorite”, “Haha” (laughter), “Wow” (surprised), “Sad” and ” Angry”. In May 2017, the Reactions suite was also implemented for comments.

In August 2015, Facebook started rolling out a new feature that allows users to broadcast their videos live (called live streams).

In August 2017, Facebook Watch was officially launched, allowing Facebook users to watch personalized videos tailored to their interests, making more interesting content available to more viewers.
Facebook has also linked up with many other applications such as Instagram and WhatsApp to facilitate communication for users.

Currently, Facebook is also the most used social network in Southeast Asian countries, according to data from Similarweb.
