A friend of mine (who is not a geek) asks me how to stop her little brother from playing web games on her computer. She is currently using Chrome and IE, and I have never done that before, even on FF.
I would prefer a solution that is simple and does not require additional applications.
Although it seems unlikely, is there a solution that works for all browsers (i.e. do it once and I never have to fix it for a new browser)?
