Cookie banner blocker for Chrome

What happens when a banner appears

1. It finds the banner's own refusal button, such as “Reject all”, “Necessary only” or “Decline”, and presses it, as you would.
2. If it finds no free Reject button on the banner itself (it does not open the banner's settings), it presses Accept as a last resort, so you are not stuck behind the banner. A Reject button whose label mentions paying or subscribing (a “pay or accept” wall) does not count as a way to refuse, and once it has pressed Reject on a page it does not press Accept there. Known ad and tracking requests stay blocked by the filter lists either way.
3. It cleans up. A dimmed or blurred background, a locked scroll bar, a page that no longer takes clicks: all of it is cleared.
4. It keeps count. The popup shows how many cookie banners it has rejected for you.

Consent tools it knows

Checked against the extension's code (version 5.5.1) on 23 October 2026. These consent-management platforms (the services sites use to run their banners) have buttons that Supreme AdBlock recognises by name:

• OneTrust: Reject and Accept buttons.
• Cookiebot: Decline, Reject and Accept buttons.
• Quantcast Choice: the two buttons of its summary screen.
• Didomi: “continue without agreeing”, Disagree and Agree.
• Usercentrics: Deny and Accept buttons.
• TrustArc: its required-only and Accept buttons.
• consentmanager: its No and Yes buttons.
• CookieYes: Reject and Accept buttons.
• Complianz: Deny and Accept buttons.
• iubenda: Reject, “continue without accepting” and Accept buttons.
• Osano: Deny all and Accept all buttons.
• Sourcepoint: Reject all and Accept all, including when it draws its banner in a frame.

Banners from other tools, and banners that sites build themselves, are handled by their wording, labels and test ids, but only inside a box that talks about cookies. It also looks inside frames and open shadow DOM (a hidden sub-tree some tools draw their banners in). Some tools, such as Termly, have no named buttons in the list: their banner is recognised by its container, and its buttons are pressed by their wording, like any other banner.

Other tools also answer banners for you. Consent-O-Matic (made at Aarhus University) fills them in with the choices you set once, and Ghostery's Never-Consent opts you out automatically; both pages were still online when we checked on 23 October 2026.

What it never presses

A wrong click on a web page can do real harm, so the rules are strict:

• Never a sign-in, OAuth or payment button.
• A button found by wording, label or test id never submits a form (except Google's own consent form) and never follows a link off the page.
• A button found by its wording, such as “Reject” or “OK”, is pressed only inside a banner that is about cookies, never anywhere else on the page.
• On pages it recognises as sign-in or payment pages by their address, it presses nothing found by wording, label or test id. Only the named buttons of the consent tools above stay active there.

Why it refuses first

Some cookie tools make banners go away by accepting everything for you. Supreme AdBlock refuses first and presses Accept only when it finds no Reject button on the banner itself.

Your refusal is saved by the site's own consent tool, as if you had clicked it yourself, so the banner usually stays away on your next visit.

When you want to choose yourself

Switch off Cookie / consent banners in Settings and every banner is yours to answer again, which helps when you want a site to remember particular choices.

Questions about cookie banners

Is the cookie banner blocker a separate extension?

No. It is part of Supreme AdBlock, together with the ad and tracker blocking: one free extension, no account.

Does it reject cookies on every site?

Not always. Banners change, and a new design can be missed. Report it from the popup with Site broken? so we can add it; until then, Hide element in the popup removes it from view.

Will rejecting cookies break websites?

It should not: it presses the site's own Reject button, so the site keeps whatever cookies it treats as necessary. If a page does misbehave, the popup can allow that site in one click.

Does it delete my cookies?

No. It answers banners and stops known ad networks from setting third-party tracking cookies. Cookies already in your browser stay until you clear them in the browser's settings.

Does it send anything about the sites I visit?

No. Everything happens on your device. For cookie banners it keeps only numbers: how many were rejected for you, in total and per day for the last 30 days, with no list of sites.
