A firefox plugin

[GoldenMerc]

Well my uncle wanted a firefox plugin to stop his son playing some game, I know he could just log onto internet explorer if it didnt work on firefox but so such, So he wants a addon that stops a certain username from logging in but not his own i think its facebook but idk. So yeh anyone know of any?

If it's fb, he could just close his sons account?

[GoldenMerc]

Yeh but there must be another way...

I don't think many commercial applications can do this, let along a free firefox addon!

Why not just block the URL of the game? That or he could block facebook on just his son's windows account.

Doubt you will find anything for free, you could just block the URL.
