The Adblock from Capital One Shopping extension works on top sites you visit while the extension is enabled. Ad blocking can be disabled/enabled on any individual site by clicking on the Adblock from Capital One Shopping extension icon in your browser toolbar, and then clicking the button in the dropdown to disable ad blocking on that website. You can also disable/enable ad blocking on all sites from the settings page here. Not all sites are compatible and you may still see some ads while Adblock from Capital One Shopping is enabled. We are constantly making improvements – if you have a suggestion for a site we should support, let us know by clicking 'Found an issue?'.
