An anonymous reader writes "Mozilla today officially launched Firefox 24 for Windows, Mac, Linux, and Android. Improvements include a new option to mass close tabs 'to the right,' as well as WebRTC support and NFC sharing on Android. Firefox 24 has now been released over 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. Compared to Firefox 23, this isn’t a big release for the desktop. Mac users will notice a new scrollbar style on OS X 10.7 and users of the browsers social features will appreciate the ability to tear-off chat windows by just dragging (full release notes: desktop, mobile)."
