(Re)enabling Pinch/Zoom in Mozilla Firefox 4 on the Apple Mac

With thanks to F Flyer for posting this.

Firefox 4 disables two finger pinch/zoom gestures on a Mac. Here is how to make pinch/zoom work again.

To enable pinch/zoom in Firefox:

• Open a new tab.
• Type in about:config and press Enter.
• In the search pane, type pinch and press Enter.
• Enter these values for the pinch.in and pinch.out prefs:

browser.gesture.pinch.in         cmd_fullZoomReduce

browser.gesture.pinch.in.shift   cmd_fullZoomReset

browser.gesture.pinch.out        cmd_fullZoomEnlarge

browser.gesture.pinch.out.shift  cmd_fullZoomReset

Well, it works for me :-)
