"Firefox, Chrome, and other browsers do an acceptable job of
downloading a single file of reasonable size. But I don't like to
trust a browser to grab ISO images and other files that are
hundreds of megabytes, or larger. For that I prefer to turn to
wget. You'll find that using wget provides some significant
advantages over grabbing files with your browser.
"First of all, there's the obvious — if your browser
crashes or you need to restart for some reason, you don't lose the
download. Firefox and Chrome have been fairly stable for me lately,
but it's not unheard of for them to crash. That's a bit of a bummer
if they're 75% of the way (or 98%) through downloading a 3.6GB ISO
for the latest Fedora or openSUSE DVD."
