that is a screenshot of me running stylish on facebook. it's purely a geek thing. what it does is give you the option of changing the CSS around on a website to make it look how you want it to look. for those familiar with greasemonkey and it changing the behavior of a site this is kind of like that only with CSS instead of JavaScript. you can get the stylish add-on here https://addons.mozilla.org/en-US/firefox/addon/2108 and you can look up user styles here http://www.userstyles.org
it's a flyers themed browser. here are the sports browsers https://addons.mozilla.org/en-US/firefox/browse/type:2/cat:26?show=100&sort=name unfortunately they do not have dolphins or .. the basketball team you like.
