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

[crarko adds: I haven't tested this one.]
