A nice showcase of the soft Elementary Project. Rated 4 out of 5 stars
A few suggestions: 1) Slightly reduce the width between toolbar icons when they are set to small. They are a little too far apart. 2) Thicken the close 'X' on tabs. It's a little too subtle.
Bug: The bookmarks icon (star) disappears when active.
(Using this theme on current Ffox on Windows XP.)
Excellent work! One of the few themes that 'gets it' and just adds icons without tons of chrome and horrible textures.
