Re: YouTube in HTML5, Firefox
The slow death of Adobe Flash has been hastened — YouTube, which used the platform as the standard way to play its videos, has dumped Flash in favor of HTML5 for its default web player. The site will now use HTML5 video as standard in Chrome, Internet Explorer 11, Safari 8, and in beta versions of Firefox. YouTube engineer Richard Leider said the time had come to ditch the aging Flash in favor of HTML5 as the latter, used in smart TVs and other streaming devices, had benefits that "extend beyond web browsers."
YouTube's move highlights the shrinking relevance of Adobe Flash on the modern internet. Adobe itself has spent the last few years severing many of its ties with the product — the company's Flash 2012 Flash roadmap narrowed its focus to gaming and "premium" video, and in 2011, the company killed Flash Player for mobile, saying at the time that HTML5 was the "best solution for creating and deploying content in the browser across mobile platforms." In 2015, YouTube has realized that Flash is not the best solution for web video, full stop.
