Change Dynamic Theme to Your Mozilla Browser
Personas for Firefox is a Mozilla Labs prototype that adds lightweight dynamic theming to your browser. It’s an experiment in personalizing.
Personas builds upon the ideas that:
* themes today are too hard to find, install and use
* graphic designers should be able to style the browser without having to code
* browsers can be more than just desktop software, they can include online components
* people just want their computer to be a little more fun and personal
* Work with Mozilla Firefox 3.0 and higher
