An anonymous reader writes with this excerpt from VentureBeat: Mozilla today launched Firefox 38 for Windows, Mac, Linux, and Android. Notable additions to the browser include Digital Rights Management (DRM) tech for playing protected content in the HTML5 video tag on Windows, Ruby annotation support, and improved user interfaces on Android. Firefox 38 for the desktop is available for download now on Firefox.com, and all existing users should be able to upgrade to it automatically. As always, the Android version is trickling out slowly on Google Play. Note that there is a separate download for Firefox 38 without the DRM support. Our anonymous reader adds links to the release notes for desktop and Android.
