Qute is a free browser theme program for Firefox users, but to truly call it "cute" may be an overstatement. This small add-on merely gives a different view of your guide buttons. Your Back, Forward, and other bar buttons won't even change colors. You'll just see some of them from a three-dimensional, slightly elevated view as opposed to head-on like the default theme.
Other than that, Qute isn't much different than the standard Firefox 2.0 theme. The background color as well as other opened browser windows remain in their default settings. If you're simply looking for a slight deviation from the norm, Qute is the perfect theme extension for you.
Qute (pronounced "cute") is an icon set that originated from the desire to make a theme for Mozilla Firefox (then Phoenix) that looked modern and blended in with Windows XP.
