While Firefox 16 isn’t due to launch until October 9, the latest version is already available for Windows, Mac, and Linux. You can grab it now from Mozilla’s FTP servers here: ftp.mozilla.org/pub/mozilla.org/firefox/releases/16.0.
If you prefer to wait for the official launch, keep your browser pointed to firefox.com. You may also want to check out the Mozilla blog, which is bound to have an announcement soon.
The biggest addition in this release, in my opinion, is Web app support for all desktop operating systems, but we’ll only start seeing the results of this new feature once developers start to take advantage (much like in Chrome). It’s also worth noting Mozilla has integrated incremental garbage collection into Firefox 16.
This essentially translates into better performance, although it will likely be very negligible on most systems. The feature improves the browser’s responsiveness by dividing the garbage collector’s work into smaller pieces. Mozilla explains:
This is a major feature, over a year in the making, that makes Firefox smoother and less laggy. With incremental GC, Firefox responds more quickly to mouse clicks and key presses. Animations and games will also draw more smoothly.
There’s no official Firefox 16 changelog as of yet, but the beta changelog should serve as a decent guideline:
