the real things is that is impossible for my extension to stop (for example) all the adsense code if someone choose "no" to ads...because anyone use a different methods to display adsense....
the only things that i've made for now is to manage analytics code (but this means that all user must use my extension to add analytics code)....
i will probably release this extension (better than nothing) or at least i will use my extension for my site only.
