By following these steps you can take advantage of the latest Firefox enhancement and disable autoplay of audio and video
Mozilla continues with its process of constant updates to its Firefox browser and before launching them to the general public they go through what is called Mozilla's testing programFor that they have the Nightly version of Firefox, which receives updates almost daily.
And in the last one that can already be downloaded from the web, the one that has the number 69.0a1 (2019-06- 17) that corresponds to Firefox Nightly 69, adds the option to block both the audio and the video that appears on the web page when we browse the net.
An enhancement to the AutoPlay section that prevents videos and their audio from starting automatically, something which can lead to savings in data traffic. The improvement applies to both web pages and social networks such as Twitter and Facebook, which already allow you to turn off the automatic playback of videos in the app."
"To be able to activate this improvement (we will do it in both macOS and Windows) we must have the most current version of Firefox and enter Preferences and then enter Options access Privacy and Security. "
Within Privacy and security we look for the Permissions box>Autoplay."
If we click on it we see how we can deactivate audio and video playback, block audio or allow audio and video. There is also a kind of white list where you can add websites that you want to leave outside of this limitation.
This is the same process in the case of using Firefox Nightly on MacOS and as you can see, the steps are substantially the same as in Windows.
This enhancement comes to Firefox Nightly in the latest update and the next step will be to wait for its availability for the stable version of Firefox.
