Description

The IAB Europe CMP Validator v2.3 checks web pages for the availability of a TCF registered CMP supporting the latest updates to the TCF introduced in IAB Europe's TCF v2.3. It verifies the availability and correct behavior of a TCF-registered CMP that supports the latest updates to the Transparency and Consent Framework (TCF) based on the control catalogue available at https://iabeurope.eu/wp-content/uploads/250412-Controls-Catalogue-TCFv2.2.pdf If no TCF CMP is found on the page, the tool will report “No CMP API found on this webpage. CMP validator cannot operate.”, indicating that the website does not implement a TCF-registered CMP.

Absolutely useless extension that should be removed from the web store. Downloaded it, tested it out, noticed that it does nothing, so deleted it, only redownloaded it so that i could leave a review. Doesnt work for its intended purpose so do not understand why its even on here. If i could give no stars, trust me, i would.

It doesn't work for me. I get the "No CMP API found on this webpage" message on all kind of websites (iabeurope.eu, google.com, onetrust.com...). I've also tried in incognito and same result.
