Mozilla has just released Firefox 24, and this refresh lavishes most of its attention on the Android version. The updated mobile browser enables WebRTC support, letting Android users conduct web-based video chats without a plugin. These surfers can also share browser tabs between NFC-capable devices, launch a preferred sharing app from the main menu, read in Braille and enable a Night mode in Reader. Desktop users aren't completely left out of the upgrade frenzy, however. Firefox 24 lets them quickly close all tabs to the right of a selected tab, drag out chat windows and use the stealthier scrollbars in OS X Lion and newer. If you're intrigued by any of the new Firefox clients, you can grab the edition you need at one of the source links.
