The release of FireFox 3.6 is a big topic in the tech communities.  Increased loading time, better page handling and personas were introduced.  Personas are a nice way to sprucing up your boring FireFox layout.  So far, there are over 35,000 different personas to pick from and the database keeps growing every day!  Amongst those are a few Spore/Sims ones for the Maxis/EA fan.  Since my FireFox header is fairly slim, none of these look right, but in your case they may be what you are looking for!  Check them out below!
