Not bad, but could be a much better. Sadly, all your saved themes disappear once you leave the Firefox Color home editing page. And, you can't install your saved theme on another machine? When you try, it gives an error message saying the file is corrupt? The editor could be better, as well.

bin mit Firefox sehr Zufrieden !!!!!

awesome...

Great Addon. Very easy to create his own theme.

This is a an easy to use tool for nearly complete customisation and it's well worth it. The only thing that could've made this better is a larger file size limit for background pictures (so i could toss literally anything on it lol). Windows Paint is enough to make a fun background to add to the colors though, and the files are small enough that I haven't had any trouble.

The customization is very good. The only unfortunate thing about it is that I can't find any way to apply it.

Amazing, would love to have the ability to have a dark new tab page similar to the classic firefox dark theme
