Beware, awful provacy policy Noté 1 sur 5 étoiles

I'm sure a lot of people don't actually read it but by installing this addon you are inviting developer to collect all the information possible. IP, history, information about device, clicks, information about extensions you are browsing and more. Please, don't actually install this plugin if you value your privacy.
