After fixing bug 136632, there are still some icons missing. In addition, some of the new ones are to light to be understood, like many of the DOM elements. Finally, the proportion of some icons, specially the ones in the navigator bar, is not correct. Some are smaller/bigger than others, unlike in the Apple version. This could be enhanced.
