Is Resource Override safe?

Clean risk

Resource Override applies user-created URL, header, and content changes across matching visited sites.

Resource Override runs on all visited pages and can redirect requests, replace loaded files, modify request or response headers, and inject saved JavaScript or CSS when a user-created rule matches the page. These behaviors are part of its resource override feature and use the URLs, headers, and page content needed to apply those configured rules.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
