Is Professor Prebid safe?

Clean risk

Professor Prebid captures Prebid and Google Ad Manager auction/debug data on pages where those ad libraries run.

Its content script runs on HTTP and HTTPS pages and injects code that listens for Prebid auction events and Google Publisher Tag details. When those ad libraries are present, it records auction events, bidder responses, user ID EIDs, configuration, and ad-slot metadata into extension storage for its popup and devtools UI.
