📃 October 2012 release notes

New in Firefox

The following features are now available in Firefox:

Animations (CSS): The animation CSS property animates an element's style over time, using keyframes described in @keyframes rules.
calc(): The calc() CSS function computes mathematical expressions such a calc(100%/3 - 1em).
2D transforms: The transform CSS property and its 2D transform functions allow rotating, scaling, skewing, and translating an element. Arbitrary 2D transforms are also possible using a transformation matrix.
3D transforms: The transform CSS property and its 3D transform functions allow rotations and other transforms in three dimensions, including perspective transforms.
Transitions (CSS): The transition shorthand CSS property sets how changes to an element's styles may occur over time. Transitions can be applied to specific CSS properties, all properties, or none.
