You may not recognize the chunky black and orange Firefox theme as a relation of Microsoft's musical Zune, but the media player served as inspiration for this sharp, nicely designed Firefox theme nonetheless. The free browser add-on looks especially striking when paired with Microsoft's own Zune theme for Windows XP. Note that Abstract Zune's publisher, Bodizzle, recommends the free get-up for those who stick to the shallow end of the add-ons pool. While we didn't experience performance clashes, some add-ons, like ColorfulTabs, are incompatible.
Version 3.0.1 changes names from Firefox Zune to Abstract Zune and supports Firefox 3.
