Is Extension HelloCSE safe?

Clean risk

Extension HelloCSE checks page hostnames against saved offer URLs and injects a discount popover on matching sites.

The extension runs a content script on all pages and reads the current page URL to derive its hostname. If the hostname matches a locally stored HelloCSE offer URL for a signed-in user, it adds a popover with matching benefits and offers to the page.
