Firefox restricted ? Puntuado con 5 de 5 estrellas

Yes, I use NoScript and yes I am now totally used to it (it's so simple (to use) though).
What I wonder about is why is there no true similar extension for Chrome and Opera browsers (they do have 'NotScript' but it is generally considered as incomparable to Firefox's NoScript), is NoScript code feasible only on Mozilla architecture or is it that the programmer lacks ?

Currently only Mozilla allows this

So far, only Mozilla has the necessary architecture bits to make an effective NoScript feasible.
