Rein, more clean and simple for Firefox

Rein, by Naoto Kusumi, is another clean, simple Firefox theme for those who appreciate invisible user interfaces while in use, and beautiful design when not.

The theme covers mostly everything: all built-in toolbar icons, sidebars, Add-ons Manager, Library, Options, Download Manager, all with a wink to good old Macintosh look. My only complain is that the buttonization of most icons in the managers results in some too small icons to be recognizable at a glance as they should be.

Get Rein at Mozilla Add-ons.
