Personas are free, easy-to-install "skins" for Firefox. Personas Plus extends that built-in functionality to give you even greater control and easier access to new, popular, and even your own favorite Personas.
Installing the add-on places a small "fox mask" icon in your status bar or add-on bar which, when you click on it, pops up a menu where you can select, change, or even randomize your Firefox Persona.
If you create an account on the addons.mozilla.org
, you can add Personas to your favorites collection there, which will then appear in your Personas Plus menu!
Even more fun is the ability for Personas Plus to automatically rotate your Personas. If you select, for example, "Random Selection from Abstract" on the "Abstract" Personas menu, Personas Plus will randomly select a new Persona from that list every 60 minutes or so, and each time you open your browser. This works with any selection of Personas, including your favorites!
