thanks again for the info. That might be a bit of overkill at 3 but who knows, maybe down the line.
in the mean time, here is a picture of the modified firefox:
As you can see the cursor is now nice and big. She is into disney princesses so I uploaded a groupshot of them into google and now it is here default background. I've modified firefox, so now all she can see and activate are preset links and move forward and backward in them. the first one (the red K) of the links is the firefox kidzui browser, which is a kiddie browser that gives them age appropriate content, no comercials, monitors their activities, give the parent a weekly report, and can be password protected.
I had to move buttons around in firefox in order to get this configuration, but overall I think it works.
