Cookie Decliner av RunicaMoe

Cookie Decliner is a lightweight, open-source browser extension that
automatically clicks "Reject all" / "Decline" / "Avslå alle" on cookie
consent dialogs so you don't have to.

It works silently in the background. There is nothing to configure and
no account to create. Open a website that shows a consent banner, and
the extension dismisses it within a moment of the dialog appearing.

Supported consent management frameworks

• SourcePoint CMP (iframe and sp API)
• IAB TCF v2.0 (__tcfapi)
• Cookiebot
• OneTrust
• Usercentrics, including the Apollo shadow-DOM variant
• Complianz
• Didomi (single-step setUserDisagreeToAll, and two-step preferences
  panels such as the one used on norskkalender.no)
• Checkbox-based consent (the MaxGaming pattern: uncheck optional
  categories, then click save)

Supported languages

Norwegian, English, German, and French. The decline-button text matcher
recognises the common phrasing in each language ("Avslå alle", "Reject
all", "Alle ablehnen", "Tout refuser", and variations).

Privacy

• No data is collected.
• No data is transmitted to any third party.
• No analytics, no telemetry, no tracking pixels.
• No use of chrome.storage, localStorage, sessionStorage, or cookies.
• No network requests of any kind.

The extension only reads the DOM of the page you are visiting in order
to find consent dialogs, and clicks the decline button on your behalf.
That is the entire scope of what it does.

Why broad host permissions?

Cookie consent banners can appear on any website, so the content script
must be allowed to run on every HTTP/HTTPS page. The extension does
nothing on pages that do not contain a consent dialog.

Open source

Full source is available at https://github.com/RuneVed/cookie-decliner
(MIT licensed). The bundled content script in the submission is produced
by esbuild without minification, so reviewers can read it directly.

Limitations

• The extension declines non-essential cookies; it cannot override
  legally required consent.
• Some bespoke consent implementations may not be detected — please
  open a GitHub issue with the URL so support can be added.
• JavaScript must be enabled for the extension to work.
