first thing they do: ask you to create an account.
if what you want is just to access blocked websites, just change your DNS to google's public dns (8.8.8.8 / 8.8.4.4) and you can access blocked sites and all your browsers will automatically be able to acess blocked sites. no need to creat an account or using an extension monitoring what you do.
