Editors' ReviewDownload.com staffJanuary 27, 2010Add some Harley Davidson badness to your Firefox browser with this free add-on. This theme, called simply Harley Davidson, adds a black background and replaces the standard icons with biker-related images.It's easily installed, and there's no learning curve. Icons haven't changed their location, only their appearance, and the tool tips remain. Instead of the regular Firefox icons, you'll see a Harley Davidson logo to go to the Firefox home page, a wheel surrounded by an arrow for the refresh icon, and a skull and crossbones to stop loading a page. The standard icons are in shades of gray, which can be a bit hard to see against the dark background. Icons for toolbars and other add-ons retain their original color.Harley Davidson fans who can't get enough of the famous motorcycle will like this free theme.
