I have Smart Zoom turned on (double-tap trackpad with 2 fingers) but it's not working. Now I'm assuming that if I'm using Firefox and I want to zoom in on the webpage I'm viewing then I simply double-tap with 2 fingers?? The Smart Zoom animation from the System Prefs / Trackpad show it working on a webpage so I'm at a loss as to why it's not working for me. Any ideas folks? PS. Smart Zoom works for me on photos in iPhoto.
