Will it notice when a plugin adds a new tracker?

Once a month it reads your pages again, and when it finds something new the Dashboard says what, with one button, Add what was found, that adds it to the banner and the cookie list. It never changes the banner by itself: until you press the button, a service it recognises, of a kind the banner does not ask about yet, is held back for everybody. A script from a site it does not recognise is listed as a new address, and goes on loading until you hold it back under What is held back. If your host blocks a site reading its own pages, switch it off under Settings → What it does.
