Mozilla today launched Firefox 37 for Windows, Mac, Linux, and Android. Notable additions to the browser include HTML5 playback improvements on YouTube for Windows computers, and improved download performance for Android devices.
Firefox 37 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.
Mozilla doesn’t break out the exact numbers for Firefox, though the company does say “half a billion people around the world” use the browser. In other words, it’s a major platform that web developers target — even in a world increasingly dominated by mobile apps.
