I spent a happy twenty minutes or so this evening fiddling with the header of my Firefox browser using their new persona option. After the automatic download of the latest version of Firefox, 3.6.8, loaded a second tab opened tempting me to personalize the look of my browser. There are a significant number of options available, including film and television, music, nature, and sports.
I quickly narrowed my search to film and tv - Despicable Me minions, Toy Story 3, and Harry Potter - and sports - most notably Pittsburgh Steelers. After applying several personas, I went with the HP book cover for Deathly Hallows. Why? I liked the colors, so many options were dark and made it difficult to locate and use browser options. This option is significantly better than the recent Google personalization because it covers only the browser header as opposed to the entire open window. Additionally, there is no lag time when Firefox opens for use. All and all, I like their persona and will probably change my mind more than once.
