Firefox 38 adds HTML5 video tag support and DRM tech for protected content

Firefox 38 has integrated Adobe Content Decryption Module (CDM) to add the ability to play DRM-wrapped content on Windows devices, and Mozilla explained the move to DRM: « We are enabling DRM in order to provide our users with the features they require in a browser and allow them to continue accessing premium video content. We don’t believe DRM is a desirable market solution, but it’s currently the only way to watch a sought-after segment of content. »
