Detecting and outsmarting an AdBlocker is trivial, but this got me thinking about the issue in terms of a security battle between a page's native script and an extension. In terms of Chrome Extensions, is it possible to protect a user from himself? Lets say the user installs an ad blocker, and its actually stealing his credit card info. Does the web developer have the means to fight the actions of the extension via native page scripts?
Is this fundamentally possible? Why or why not?
