Since this is walmart.com, the CSS rule should be ignored and the element should not be hidden. The current workaround is to change the rule set to the following: [ { "trigger": { "url-filter": "^https?://" "unless-domain": ["*walmart.com"] }, "action": { "type": "css-display-none", "selector": ".sponsored-container-bottom" } } ] This is not ideal because it would only work if walmart.com is the top URL, not if it's an iframe.
