I've used this addon before and since they've updated it and improved everything I was unhappy with, I'll give it 5 stars.
They should implement this in the next update just so you don't need to hunt for something like it.

Every time I create theme I have no way of saving it. I would see it at the beginning and then when I done with my theme I can't save it.

wonderful make your own skin theme, i love it

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...
