I want to protect a webpage's data from the extensions which have permission to read the site's data. I guess some kind of protection must be done on the client side for this purpose. As per my knowledge, there can be two methods using the default Chrome browser; first use javascript or second use a custom extension. But I am doubtful whether any of them can identify the presence of the extensions which have this permission.
Any other method for accomplishing the tasks is also welcome.
