In the latest build for Firefox Nightly, Mozilla has introduced the ability to automatically block videos with sound that play immediately whenever a website is accessed. This feature comes with version 63.0a1, as was announced in Mozilla"s Roadmap earlier this year.
The feature was announced by Firefox developer, Dale Harvey, and it will give users the ability to either mute all sites that automatically play media with sound whenever accessed, or to select each time any such website is visited whether or not the media should be blocked. Of course, autoplaying can be allowed as well, if the user wishes it to be so.

Audio elements that play as soon as a web page is loaded will trigger a popup notification under the URL address bar if the "Always Ask" option is selected, as can be seen in the video above. However, videos that do not contain audio or are muted by default won"t be blocked by this feature.
It should be noted that a similar feature was added to Chrome in March, while Edge also introduced the ability to block autoplaying videos to Windows Insiders last month. Firefox users interested in making use of this feature can download the latest Nightly release from Mozilla"s website, as the feature will probably take some time to roll out to the Beta version and subsequently the stable channels.
