There’s a lot more in the theme than just simply changing icons — I have fixed the look of the tabs, reordered buttons, changed spacing, added icons to menus, buttons, and other appropriate places, modified the way various widgets work, and a lot more.
A lot of us have been using this theme for a while now around Novell and it really makes Firefox feel like a part of the desktop. Today, I’d like to announce the public pre-release of Industrial for Firefox.
I’m still developing the theme, so please note that it will probably change from time to time. Also, I plan on adding update support and will most likely add it to updates.mozilla.org sometime soon as well so it should be easier to update in the future.
