This is a
cookie consent banner — specifically a GDPR/privacy compliance popup. These are legally required across the EU and UK (where you're based) under data protection laws.
Why it keeps appearing:
The banner stores your consent choice as a cookie. If an adblocker is deleting tracking cookies (including the one that records "user already consented"), the site forgets your choice and shows the banner again on the next visit or page load.
How adblock causes this specifically:
- Many adblockers (uBlock Origin, AdGuard, etc.) block or delete consent-related cookies and scripts from frameworks like OneTrust, Cookiebot, or Quantcast — which is exactly what this banner looks like (note the "1724 Partners" tab, very typical of IAB TCF consent frameworks)
- Some filter lists specifically target these consent banners, which can block the "save preference" function from firing properly, so even clicking "Reject all" doesn't stick
- The adblocker may also be blocking the script that checks whether consent was already given, so the site defaults to showing the banner again
Solutions for the user:
- Whitelist the specific site in their adblocker so consent can be saved normally
- Use a browser extension like "I don't care about cookies" or "Consent-O-Matic" which auto-clicks reject and handles the consent storage properly alongside adblockers
- In uBlock Origin, they can allow localStorage or cookies for that domain specifically
The banner itself is legitimate — it's the adblocker interfering with its memory of the user's choice.
