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?
