It’s your lucky day. Meet personas, a special type of add-on. You can use them to celebrate holidays and personal victories or switch them out to whatever suits your mood. With over 30,000 designs in every color, pattern and topic imaginable (we found over 10 options for St. Patrick’s Day alone), you’ll find something you like. Personas are a cinch to apply. You don’t even have to restart Firefox, and when you hover over a design, you’ll automatically see a preview. And if want to change it, you can go into your add-ons manager (Tools –> Add-ons –> Themes) to un-install and apply your other personas.

See, add-ons really are flexible—even if you’re a bit…green. So check out some St. Patrick’s Day personas today!
