When looking for kid friendly themes, there are not that many to choose from out there. The best of the best, better than all the rest is the Scribblies set of themes for Firefox. For more kid friendly themes check out Percy’s suggestions over at Mozilla Links.
Try out Scribblies Plain for a dull background but fun icons!
Need something more colorful? Try Scribbles Brite!
Also can’t forget about Scribblies Kids for an alternative look and feel!
I really love the entire line of Scribblies themes for Firefox. Which one is your favorite? Maybe you’ll have an easier time picking a favorite than me.
