Personas allow you to “skin” the top and bottom areas of Firefox only (the header and footer of the browser chrome) without any change to the look of the navigation buttons or menus. With Personas, you can easily switch between many different lightweight skins with no further installation required.
Like Personas, a Firefox theme is a type of Firefox add-on that extends the functionality of your browser and allows you to “skin” it in a variety of ways. However, unlike Personas, a theme changes the appearance of navigation buttons, toolbars and menus.
Personas are lightweight “skins” that change the look of your Firefox web browser. You can easily switch between Personas with just a few clicks. There are hundreds of Personas to choose from, with more added every day. You can even create your own and share it with others.
In less than 60 seconds, you can install a Persona and transform the look of your Firefox web browser. Visit GetPersonas.com and click the download button. After installation, you will be asked to restart Firefox.
