Consent fatigue is real. You see the same banners on every site, every visit. navigator.consent makes consent assistants reliable enough to handle it for you. Set your preferences once. They follow you everywhere.
Cookie banners are not popping up every other day because they like to annoy you. The hard truth is that Consent Management Platforms currently need to use the same mechanisms to store your preferences as every other third-party service. Yes, cookie banners use cookies to persist the consent state. However, these cookies have a hard time sticking due to factors outside the CMP’s control.
Safari’s Intelligent Tracking Prevention caps client-side cookies to 7 days. Firefox Enhanced Tracking Protection applies similar restrictions. Since most CMPs store consent with document.cookie, your choices are silently erased, and the banner comes back as if you never decided.
When you tap a link in Instagram, TikTok, LinkedIn, or a news app, it opens in a sandboxed WebView that cannot access your main browser’s cookies. Every page load looks like a brand new user. This is a growing share of mobile traffic, and no CMP can work around it.
A 2025 study found that 38% of GDPR-compliant cookie banners still use aesthetic manipulation: highlighted "Accept" buttons, buried reject options, pre-checked purposes. EU websites are 48% more likely to use these tactics than non-EU ones. The design is meant to tire you into clicking "Accept all."
Browser extensions already handle consent for you. But today they work by reverse-engineering each CMP’s interface. navigator.consent gives them a standard channel instead.
Extensions like Consent-o-matic, SuperAgent, and Taste scrape each CMP’s DOM: guessing button selectors, injecting clicks, reverse-engineering vendor lists. Every CMP update can break every extension. It’s a constant maintenance treadmill.
CMPs declare vendors and purposes through a structured API. Your assistant reads this metadata and applies your preferences. No scraping. No guessing. One integration that works with every CMP.
You install once, set your preferences, and the assistant handles every site you visit.

Your choices always override automated ones. If both your assistant and a CMP set a preference, your explicit decision takes precedence. The system tracks provenance: who set what, and when.
The audit timeline logs every consent mutation with timestamps and provenance. You can see exactly what was set, by whom, and verify nothing happened without your knowledge.
You can withdraw consent at any point through your assistant or directly through the CMP. No lock-in.
You don’t need to understand APIs to benefit. Install a consent assistant extension, set your preferences once, and let it handle consent banners for you. The extensions below already work today, and navigator.consent will make them even more reliable.
