Okay, so I am using a MacBook Pro purchased from the Apple store a month or two ago. I'm a lifelong Apple user and am having a problem! All of the sudden when I use my internet (firefox 4-- is the problem with this; although I've been using it since it came out and this is my first major issue besides Netflix) I cannot minimize or maximize content size within a window by "pinching" on my trackpad. I know this is really a trivial issue that may or not have to do with my mac, but it is extremely annoying nonetheless. Thanks for any help!
