Open source supporter Mozilla has today announced the arrival of its latest Firefox release, Firefox 12. This build brings a stealthier update system on Windows (it removes the user account control dialog pop-up), multiple security fixes, better WebGL performance on Mac OS X, automatic downloads for URLs pasted into the download manager window, support for the text-align-last CSS property and for the ECMAScript 6 Map and Set objects, and a few more tweaks and improvements.
