Mac users who’ve recently installed OS X Lion (Ver. 10.7) may have noticed the touchpad’s “pinch-zoom” function no longer works in Firefox. (It still works in Chrome, but not in Firefox.) Distressing, since this was one of the Mac functions I’d very quickly come to love. I prowled around a few forums and discovered that while a lot of people have noticed the problem, no one had a real fix.
I appealed to my son, who always seems to have or find good geekly answers for my un-geekly issues, and he came up with the following. It seems to have solved the problem.
Type the following into the address bar: about:config
Then use the filter (top left side) and type the word: Gesture
Make the following changes to the following 2 fields:
browser.gesture.pinch.in ~ enter the field and type: cmd_fullZoomReduce
browser.gesture.pinch.out ~ enter the field and type: cmd_fullZoomEnlarge
At some point in that sequence, a warning popped up asking if I was sure I wanted to proceed, and I forged ahead. Admittedly, I have an expert on call if I screw anything up, but it all seemed very straight forward. I just triple-checked my typing before entering anything.
In typical Mac fashion, which still unnerves me two months after my switch from a PC, there is no place to click “Okay” or “Enter” or “Done.” I didn’t even see a place to close the window I’d been in. So I just closed Firefox, prayed, and reopened it. Voila!
