About this extension
CookieConsentMate lets you set your cookie preferences once, and then handles every consent banner automatically — silently, instantly, and according to your exact choices.

How it works
  1. Click the 🍪 icon in your toolbar
  2. Choose which cookie types you consent to (analytics, marketing, personalization)
  3. Browse freely — CookieConsentMate does the rest

Features
  • ✅ One-time setup — configure once, works everywhere
  • 🚫 Auto-handles banners — clicks "Reject all" or "Accept all" based on your settings
  • 👁️ Hides banners after handling so they never flash on screen
  • 🔢 Session badge shows how many banners were handled
  • 🌍 Multilingual — supports banners in English, French, German, Spanish, Italian
  • ⚡ Lightweight — no external dependencies, pure JavaScript, zero tracking
