To control Whackamole, click the 
icon in the Chrome extension toolbar. Then click on the link shown in the popup window to enable or disable Whackamole for the current site. This is what the popup looks like:
Privacy
Whackamole never connects to a server and never inspects the data on the sites you visit. Instead, it looks for elements that look like ads and hides them using a set of builtin rules.If you disable Whackamole for a given site, that site's URL is stored in the local browser history on your machine. Other than that, Whackamole does not store any data, does not analyze your sites, and does not track your browsing behavior at all.
Implementation
We suggest you take a look at the source code to verify how Whackamole works. The implementation is simple and should be easy to understand. The recipe for the main script covers only 76 lines of JavaScript:
- Whackamole watches the current page for any changes.
- Whenever the page changes, a timer is started.
- When the changes settle down, the timer runs.
- Elements that contain ads are marked and hidden.
The recipe for the popup script is even simpler:
- Add a link to allow toggling the current page.
- Add a link to the support page.
Happy browsing!
