That's the UI used in Safari 6. It's pretty terrible, in my opinion; it hides too much information in a single button. It's roughly equivalent to Chrome's download bar, except with less information.

What info do you need?

If I am downloading more than one item (and maybe I am waiting for a particular one), it's not telling me which ones are finished.

OS X postfixes files that are being downloaded with .download – so if you're looking at a file, you should see if it's done or not.

I like this. It is one less window to manage.

Safari has publicly had that since October 20, 2010, and of course it was worked on privately before that. That screenshot looks like it's from April of this year?

I actually liked the download window in FF, and find this new UI (been using it on Nightly for a while) pretty annoying.

Agreed. Maybe I'm just too used to the download window, but I tried the recent Firefox nightly I instantly cringed when I downloaded a file. I prefer Chrome solution to both.

Too bad they didn't patent it.
