Internet Child Protection?

Hi Folks, Was wondering what internet program or browser will keep my 9 year old daughter away from accidental mayhem/porn. She typed in "disney" incorrectly and got "dice ny" or something. Not bad, but could be worse. I remember in Internet explorer a slider bar thingy. I can't seem to find anything here in Mozilla. Thanks. Thom Nuzum Washington DC (just got back from Slackware 10, very impressed though the hardware detection on my home built was overly time consuming--keeping suse 9.1 here. It did setup out of box on HP Athlon Laptop better than suse. Boots twice as fast 2)
