A dark metal theme with sharp contrasts. It will definitely draw attention.
Silvermel
Silvermel is silver, shiny and quite unobtrusive. The transparent effect for tabs is awesome.
This Mozilla Firefox skin is not revolutionary, but it has a fresh look with nicely designed tabs. If you keep on reading you’ll see that I’m a little obsessed with pretty tabs.

Anthem is a very stylish template in dark and light grey. I love the look of the tabs. The icons are exceptional and they’re smaller than with most themes, which saves space and gives more room for browsing. This one is my new personal favorite.
A playful theme for your kids or the kid in you. Gotta love the icons in the navigation toolbar. Also the tabs are quite original. Definitely something different!
This is the theme I’ve been using for years. It’s clean and simple and also available in three more flavors: pure, metal and smooth.
Simple Green reminds me of Netscape. If you still mourn the end of IE’s first serious rival, express your grief with this theme.
This theme made the list because it has a refreshing set of icons and very lovely shaped tabs and boxes. I’m still a huge fan of rounded edges.
If you’re using a Vista transformation pack on XP, you can’t do without a Vista Firefox theme. So this one’s for you!
One of the few dark Mozilla Firefox skins that are actually stylish. NASA Night Launch is very cool. Pretty tabs, well-designed icons and a very clean, dark look.
I love the fox in this theme. But also the buttons and tabs are pretty cool. If the animal is a little too much for you, there is one without it: Utopia White.
Here’s a very soft and girly skin with lovely pastel colors and roundish icons. Yes, we do have female readers! Girls, where are you?
Girls play Xbox, too! Maybe that’s why this theme isn’t exactly virile. Or is this just a very modern design?
Here’s one for the guys. Chrome, stone, levers and rounded edges so that you don’t hurt yourselves. I love the levers. Makes me think of Myst. And get this: they’re actually animated!!! How cool is that?
Finally, here’s a theme that will give Firefox a Chrome-like look, including tabs on top.
Now , I hope your Mozilla is pretty rocking. It feels so cool to work on a colorful Browser.
