Description
Bloqueur d’UTIQ
- Utiq is an advertising identifier created by 36 European telecom operators (Orange, Deutsche Telekom, Vodafone, Telefónica) that tracks users via their internet connection rather than through cookies, rendering standard protective measures (clearing the cache, incognito mode, switching devices) ineffective.
- The Utiq identifier applies to your entire household, not just you: if someone else accepts it on your connection, their browsing activity gets mixed in with yours under the same label, unlike cookies, which stay within a single browser.
- Utiq uses CNAME cloaking to impersonate the site itself and bypass tracker blockers, but you can block it in 30 seconds at consenthub.utiq.com or opt out on every site that implements it.
Install
- Unzip the file
- Go to chrome://extensions/
- Enable Developer Mode (top right)
- Click “Load unpacked extension”
- Select the utiq-detector folder
- Enable the extension
- Enable blocking in
Utiq detector
What the plugin detects
Network fetch/XHR/Beacon
Intercepts all requests to utiqcontent.com, utiq.com, etc.
DOM scan
Detects script, iframe, and img elements pointing to Utiq, including those dynamically injected (MutationObserver)
CNAME via DNS-over-HTTPS
Requests to Cloudflare DoH to resolve the CNAMEs of ~12 common subdomains of the visited site
CNAME chain
Recursive resolution: if a CNAME points to another CNAME that points to Utiq
Block
The “Block Utiq” toggle uses Chrome’s declarativeNetRequest API (MV3) to natively block requests to all known Utiq domains-without a proxy, directly at the browser level. A badge changes color: red ⚠ if detected, green 🛡 if blocked.
