I got my MBP about a year ago and love it. I am learning new things every day. There is one thing that is bothering the crap out of me. I got a Magic Mouse yesterday and I can not for the life of me figure out why when using Firefox I can not go back using the gesture. I have looked at the system preferences and have done what it says. I don't understand why this is not working for me. Does it have to do with the fact that I am running Lion or firefox? Is this gesture just set up for Safari? Need some help here please. Thanks guys.
