Why when I go to use a program I installed (this only seems to happen with Firefox) a picture of a removable drive (the same kind you get when you plug in your flash drive) comes up on the desktop only it has the Firefox icon on it? Does Macintosh think Firefox is a removable drive or something?
This is probably a stupid question but we just got an iMac yesterday and I've never used OSX outside of school where they have everything locked down.
