After downloading and installing firefox on my new macbook, this icon (pictured here: http://imgur.com/Qp11N.png ) would register on the desktop screen and the window for it (pictured here: http://imgur.com/xgYqy.png ) would always pop up everytime I open firefox. I tried dragging the icon into the trash bin, but I would always get "the disk 'firefox' is in use and could not be ejected" popup (pictured here: http://imgur.com/mqTb8.jpg ). How do I go about in deleting this item? Someone told me to eject the disk img, I tried doing that but the popup "the disk 'firefox' is in use..." would continue to spring up. From what I've read, I guess the reason the disk img won't eject properly is because I'm running firefox from the disk img, if so, how do I stop that from happening?
