CookieOnce

About

Every website now has a cookie consent banner. Every single one. You click "Reject All" 20 times a day. Some sites make you click through 3 screens. Some don't even offer a reject option on the first page.

CookieOnce sets your preference once and handles every banner automatically, forever.

What It Does
CookieOnce intercepts cookie consent banners before they fully render, applies your preference, and dismisses them silently:
- Reject All Cookies — Automatically declines all non-essential cookies on every site by default (the privacy-respecting choice)
- Instant Dismiss — Banners are handled at document_start, before you even see them flash on screen
- 95%+ Coverage
- Zero Interruption — No flashing, no clicking, no waiting — the web feels just like it did before GDPR banners
- Choose Your Mode — Switch between Reject All, Essentials Only, and Accept All with one click
- No Account Needed — Install once, choose your preference, use forever on every website

Cookie Banner Coverage
CookieOnce handles banners through multiple strategies:
- Pattern-based button detection — finds "Reject All", "Decline", "Necessary Only" buttons
- Structural detection — identifies banner layouts from 200+ common CSS patterns
- iFrame CMP support (all_frames: true) — handles banners loaded inside iframes

Who It's For
- Everyone — cookie banners are shown to every internet user
- Privacy-conscious users who want to reject non-essential cookies
- Power users who want a cleaner, faster-loading web
- Developers tired of cookie banners interrupting their workflow
- Anyone using GDPR-compliant websites (EU visitors especially)

Modes
Reject All (default) - Declines all non-essential cookies
Essentials Only - Accepts only technically necessary cookies
Accept All - Accepts all cookies (faster loading, more tracking)
Disabled - Lets banners show normally

How It Works
1. Install CookieOnce — it works immediately
2. Choose your preference: Reject All is selected by default
3. Browse the web — every cookie banner is dismissed according to your preference
4. Never think about cookie banners again

Privacy
CookieOnce does not harvest your data. It does not know which sites you visit. It processes everything locally using pattern matching. No usage data is collected.
