Hi Helen and thank you for the compliment and the rating. You add whatever one is your favorite to your browser that's what you do with them. If you go to the Mozilla software page and get the Add On called "Personas Plus" then you can add any persona you wish plus have other tools and stuff related to that software at your fingertips. Also you can add each favorite persona to your Favorites folder when you are on that particular persona's detail page, so you can collect a lot of favorites and the folder shows in your browser under Tools, Personas, Favorites. Hope this helps! Thanks once again for the great review!
