Google-chrome – How to disable HTML5 content in popular browsers like Firefox and Chrome

browserfirefoxgoogle-chromehtml5video

The bad thing about Flash video was that it required a third-party plugin to play the content. The good thing was I could select which content to play; using the click-to-play feature in Firefox and Chrome.

But now that HTML5 video is getting popular, I see a lot of ads popping into view again. They are not only a distraction, they hog resources on my computer and make the fans spin full speed.

Is there a way to disable HTML5 audio/video content by default, and enable it only selectively?

In Firefox you can set media.autoplay.enabled to false in about:config though as of now this may not be sufficient for every case. An extension like NoScript (default settings) could be used to complement the missing functionality or even otherwise used by itself without the about:config setting. In NoScript it's also possible to extend the functionality to whitelisted sites (NoScript Options > Whitelist) via NoScript Options > Embeddings: Apply these restrictions ...
