You may want to set a site-specific block. You can do this any of 3 ways: # Visit the site and use the Permissions tab of the Page Info dialog # Use the cookie exception dialog in the Privacy tab of the Options dialog # Use the about:permissions page (if any permissions are already set) For #1: While viewing a page on the site, open the Page Info dialog using either: * right-click and choose View Page Info > Permissions * Tools menu > Page Info > Permissions * click the padlock or globe icon to the left of the address in the address bar > More Information > Permissions Here you can set Set Cookies to Block. Then switch over to the Security tab > "View Cookies" and remove what has been set. For #2: orange Firefox button (or Tools menu) > Options > Privacy If you can't see the "Exceptions" button, change the history drop-down to "Use custom settings for history" so you can access it. Then create a new block for the unwanted domain. For #3: Type or paste about:permissions in the address bar and press Enter. Wait for the list to load and look for amung.us in the left column. If it's there, click it to open the associated permissions panel where you can change the cookie permission and clear any already set cookies. Success??
