Under Mac OS X, Firefox should zoom when the zoom multi touch action is used on the touchpad: (Example: https://commons.wikimedia.org/w/index.php?title=File%3AGesture_Unpinch.ogg ) Safari is doing that very well. Chrome is quite slow.
For more context, this has been disabled by default in bug 613909, having it available as an option has been reported in bug 632733 but nothing ever happened.
This sounds like a dupe of bug 688990.
