Firefox 24.0 is now available today with a variety of modest changes for the Linux / OS X / Windows version while Firefox for Android has some of the more interesting features this round.
Users of Mozilla Firefox 24 on the desktop now have a "close tabs to the right" menu item when closing tabs, the ability to tear-off chat windows from Firefox Social via dragging them away, major SVG rendering improvements with image tiling/scaling, an improved and unified Browser console for developers, and support for W3C touch events has been disabled until the feature is properly implemented within Firefox.
Firefox 24 for Google Android devices meanwhile is now enabling WebRTC support by default (it's already been done on the desktop side), support for sharing open tabs with NFC-enabled phones, a night mode function for the Firefox Reader, easy access to favorite share applications via the main menu, and various other alterations.
Those wanting to grab Firefox 24.0 right now can find it on the Mozilla FTP server
while details on the quick browser update can be found for now via the beta release notes
until Mozilla volley outs the official release information.
