Crumb 作者： Ryan Curran

Cookie consent banners are the worst thing about the modern web. Every site, every time — the same pop-up asking you to "manage preferences" or "reject all," most of them designed to make rejecting harder than accepting.

Crumb makes them go away.

It hides cookie banners with a stylesheet built from Fanboy's Cookie Monsterlist plus a small curated overlay for sites that need extra coverage. The browser's built-in declarativeNetRequest engine blocks the consent-management scripts at the network layer.

That's the whole extension.

What makes Crumb different:

• Zero telemetry. No analytics, no crash reporting, no usage metrics. No background script. Nothing leaves your browser, ever.

• No remote calls. The block list is bundled with the extension at build time and never updates over the network. New rules ship as new versions through AMO, like every other extension you trust.

• No auto-clicking, no scripted UI interaction. Crumb does not press "Reject All" buttons or interact with consent dialogs. Sites that respect GDPR will treat a hidden banner as no consent given.

• Open source under MIT. Every filter and every line of code is on GitHub. The build pipeline that turns filter lists into the runtime is plain JavaScript — no minification, no obfuscation.

• Minimal. The runtime is event-driven — no timers, no polling. No options page, no settings to misconfigure.

Why "Crumb"?

Because we don't give one about cookies.
