Hey everyone,
I just finished up the basics on a new extension I'm working on called Customizer.
If you've seen the 'userChrome.css' tweaks around the internet that you can use to add, remove and change some elements in Firefox, you know that no one site has them all and even if they did.. they're not that easy to get working.
So I created this extension to do the dirty work for you, it will create the file and edit the file and all you do is check some boxes.
You can hide menu items, menus, icons, search bar, magnifying glass... you can change fonts, colors, sizes... all kinds of things. And the interface is super easy to use.

There will be a lot more added to it in time as I get to it, but for now I think it's a great start for a beta. So if you like FfvB and would like to have a little more control over what Firefox looks like (this is not a theme however)... then give it a try and leave me some feedback.
Oh, and to give you an idea, here's a couple of screen shots:
