We have had are Macbook for about three months. My wife is used to windows and so am i. We are both having an easy time swithching to the Mac. I Love it, but every since i downloaded firefox which i am not using, me and only me out of four user is the only one having a problem downloading anything. Every time i try to download it acts like its going to start but nothing. Everyone else is having no problem. When i download nothing happens not even in the download screen. I have my selection set up to download desktop. I can't get new widgets or anything only my user is having this problem. Please help, and tell me what i may have done or switch unknowingly. Travis S
