For Australis, the downloads panel will be updated with a new style: https://www.dropbox.com/s/pyhmgkdl0gebzo5/Arrow-Panels-OSX.psd This includes: - Styling the general popover element to light gray - Styling the footer element of the downloads panel to a slightly darker gray - Styling the downloads list to spec (text spacing, new icons) - Implementing a download count in the footer

Should depends on bug 759397.

Do we really want to use the native progress bars for the download panel (especially on Windows)? Why not use a thinner and classier design that would use less vertical space.
