Disable Auto-playing of Videos in Facebook(PICS)

Whenever someone posted a video on their Facebook profile, these videos did not play unless you tapped on the video thumbnail. But Facebook has changed this with the newest version of their app. Now if you scroll through your Facebook feed, it will start to play the videos automatically without you having to tap on their thumbnails. This is very similar to how videos are handled on Instagram, another app owned by Facebook.
The problem is that this setting (auto-playing of the videos) works under all types of networks – including WiFi and mobile data. If you are using an expensive mobile data pack, then you should disable the auto-playing of videos on Facebook in the following manner:

STEPS:

1. Launch the Facebook app in your smartphone and press the menu button. From the menu that appears, select Settings to access Facebook settings.
2. On the setting screen, scroll down and tap on Autoplay option.
