• (2025-02-26) Sergio U: 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.
• (2024-06-19) Yoav Baras: Very very useful extension for anyone dealing with GDPR / Consent management.
• (2024-03-28) Heinz Baumann: In the latest version 2.2.6, we have resolved two key issues: 1. Previously, at the initial CMP state (where CMP is displayed but no user action has been taken), our validator detected the presence of a CMP API but failed to populate any results from TCF API calls. With this update, the CMP validator will correctly populate the summary and API sections with values retrieved from TCF APIs. 2. Since version 2.2.4 (released on December 7, 2023), our CMP validator attempted to load a file from https://vendor-list.consensu.org/v3/archives/vendor-list-vundefined.json in cases where there were errors loading basic CMP data, resulting in a 403 Forbidden error. This issue has been rectified."
• (2023-11-06) Simon Bennett: Improved extension, which helps you audit TCF compliance from your Consent Management Platform. Further improvements could include (1) adding support for Google ATP vendors (2) providing feedback to publisher/CMP Vendor / IAB Europe on misconfigured CMPs (e.g. loading too late, not firing, etc) to drive compliance. My guess is the tool is used almost exclusively within the digital media industry so later would be useful.

• (2023-09-18) Simon Bennett: Very useful plugin for those working in digital advertising and privacy in Europe. Allows you to see vendors and purposes collected in a consistent downloadable format. Would like to see blocking of add in removed from sites, ability to use on Quebec TCF and GPP sites too.
