Ever wanted to control cookies like a digital ninja? πŸͺπŸ’₯

In this beginner-friendly tutorial, I walk you through how to create Cookie Guardian, a lightweight Chromium extension that lets users:

  • βœ… View & delete cookies
  • 🚫 Block domains from setting new cookies
  • πŸ”“ Unblock domains at any time
  • 🎯 And filter cookie lists with ease

No React. No fancy tooling. Just HTML, CSS, JS β€” and a sprinkle of Chrome APIs.

Perfect for:

  • New devs curious about browser APIs
  • Side project tinkerers
  • Anyone who’s ever said β€œWait... I could totally automate that.”
