Not working properly in 11 Rated 2 out of 5 stars
This add-on looks wonderful in the screenshots, but the effect seems to be minimal in Firefox 11 aside from the back/forward buttons. I would love it if 11 could look as clean as 3. I've linked a screenshot below of what it looks like when applied to 11. Thanks for your work.
This is because you haven't customized the browser. Once the theme is installed, you need to right-click the toolbar and click 'customize'. Then you can drag icons into place, show icons and text, and disable 'small icons' if you wish.
