Rated 4 out of 5 stars
DNTMe is very good add-on, but I have few complaints. I guess the overlay is html which is kind of annoying. When you press the icon, you must specifically press the close button to close the window. Compared to ghostery, you can click anywhere on the screen, the window closes. I find it convenient.
My other complaint is I block social buttons with ABP, but DNTMe recreates these social buttons. May be you should have some options for users to tinker such things. I find the social buttons, graphs kind of annoying and unprofessional. Overall I still like this tool, but if you can make few GUI changes it will be much better.
