Today Mozilla released the final version of Firefox 16, which includes a number of new tools for developers. "A number of HTML5 code has been 'unprefixed,' which means that Mozilla has decided it has matured enough to run in the browser without causing instability. The newly unshackled HTML5 includes CSS3 Animations, Transforms, Transitions, Image Values, Values and Units, and IndexedDB. Two Web APIs that Mozilla helped to create, Battery API and Vibration API, are also now unprefixed. These changes help keep Firefox competitive, but it also sends a signal to developers that Mozilla thinks these are good enough to begin baking into their sites. It's a strong endorsement of the 'future-Web' tech." Here's the complete change list and the download page.
