Hi yoshi, thanks for using Ghostery.
I'm not sure I understand what exactly you are asking here, tho I'll assume that you merely want to enable blocking in your Ghostery for Chrome and answer that. Let me know if this is not what you meant.
In Chrome, install Ghostery from our web site. Once installed, click on the Ghostery icon and select options (the blue icon with clock wheels). This will open Ghostery Options page. Scroll down to "Enabled Bug Blocking" checkbox and checkmark it. After that you need to select the companies you wish to block and finally, press Save at the bottom. Your Ghostery is now configured for blocking.
