I have an iMac Desktop with OS X Leopard. I want to download Firefox 3.6 There are three options for how to save Firefox 3.6 and I don't know which one I'm supposed to choose. One just says SAVE; the other says something about a Diskimage? default; and the third I can't remember. Which one do I choose before beginning the download? == This happened == Not sure how often == I chose to download the new 3.6 version of Firefox
