Okay I'm just releasing a mod of different themes that I've combined to fit my taste.
(IE7FoxVista that utilizes elements from juneyong's VistaFirefox theme and also from dlb's FirefoxVista theme)
It should also work with firefox 1.5 but I didn't try it.
After installing the theme and the extensions you will also need to put this in your user chrome.css in order to get rid of the addressbar go button and the border of toolbar menu.
* Remove toolbar borders*/
toolbar {border-top: none !important; border-bottom: none !important}
/* Remove toolbar separators */
#toolbar-menubar {
min-height: 12px !important;
padding: none !important;
margin: none !important;
border: none !important;
}
#nav-bar {
padding: none !important;
margin: none !important;
border: none !important;
}
#PersonalToolbar {
border: none !important;
}
#navigator-toolbox {
  border-bottom-width: 0px !important;
}
#urlbar-container
margin: none !important;
border: none !important;
padding: none !important;
}
/* Remove toolbar borders*/
toolbar {border-top: none !important; border-bottom: none !important}
/* Remove the search-go-button and fix searchbar spacing */
.search-go-button {
display: none !important;
}
#go-button {
display: none;
}
And in order to put the elements at the right place follow this guide from the orignal author of the theme.
