Why Facebook video autoplay is potentially dangerous, useless and how you can deactivate it

If you want to skip my rant about security and see how to do this, jump to the HOW TO areas below.

Why Facebook video autoplay is potentially dangerous?

Here are a couple of reasons why I think that autoplaying a video is potentially dangerous:

– Facebook videos use on Windows Adobe Flash Player to render. I am not sure what they use on mobile devices where there is no Flash. I guess that If the browser supports HTML5 than uses it, if not, then there is no rendering. According to Secunia, FlashPlayer is on top 5 from 50 on the most vulnerable software.

Now, imagine that someone finds a vulnerability in the player that can be exploited with a special video file. Guess what would happen… by default … Everyone who has this feature active, and this means everybody who DIDN’T manually deactivate it, will be affected. Yes, it is probably not realistic to have something like this… but also SSL was considered bulletproof.

– Some people use Facebook at work and imagine that a video with content not recommended for office starts to play automatically.

Fortunately,, the audio is by default off, so no  reason to raise attention with strange noises. But what if you want to show a post to some colleague? Pretty embarassing if the content is not suitable for office.

Why Facebook video autoplay is useless?

– It consumes bandwidth! A lot of it. If you are on a mobile phone, you can configure it to run only on wireless.

– Slows down the FB experience. Especially if you are on a tablet of smartphone.

– I have a lot of videos on my timeline added by others. I am almost never visualising them.
