Check the boxes on the Ad List that are next to the ads you want to block, as shown on the right. If you can't find the ad in the Ad List, your browser's cache might be preventing it from being downloaded. As soon as the page has finished loading, follow the instructions above. Read more about how your browser's cache affects ad blocking here . If you still can't see the ad in the Ad List, then the ad might not be a graphical ad.
Some ads are text-only or are forms formatted to look like ads.
The Guidescope service only blocks graphical ads. Non-graphical ads don't show up in the Ad List.
