I'd like a good sking for Firefox 3

I've looked for a good skin for firefox 3 but so far have not found one. Does anyone know where I can get a good one. I favour a bluish color scheme and easy to read buttons.........and does anyone know where I can download a zoom in and out button for Firefox 3 ? know I can use CONTROL + or - but a button would be more groovy.

Here are 3 of them:

The one I'm currently using now:

The first one I installed but the scroll bar is too narrow. Is there a way to widen it?
The rest of the skin is excellent.
Thanks.

You're welcome. But you can't widen the scroll bar unfortunately.
