Cookie Setter di GinjaNinja

Cookie Setter automatically injects cookies into websites whenever you visit them, ensuring your preferences are always restored, even after clearing your browsing history or cookies.

Perfect for:

🌙 Restoring dark mode preferences on sites that store your theme choice in a cookie
🔒 Persisting login preferences or consent banners you've already dealt with
⚙ Maintaining site settings that would otherwise reset when you clear your history


How it works:
Simply add a cookie rule by entering the domain, cookie name, and value. Cookie Setter runs silently in the background and automatically sets your defined cookies every time you visit a matching website, no manual effort required.

Features:
✅ Set cookies for any domain and its subdomains
✅ Control cookie path, expiration, SameSite policy, and HttpOnly flag
✅ Enable or disable individual rules without deleting them
✅ Supports session cookies or custom expiration by days or date
✅ Skips setting a cookie if it already exists — no unnecessary overwrites
✅ Clean, simple interface to manage all your cookie rules in one place

Your data stays yours. All cookie rules are stored locally on your device using Firefox's built-in storage.

Tip: Visit a site, use your browser's developer tools (F12 → Storage → Cookies) to find the exact cookie name and value used for dark mode, then add it as a rule in Cookie Setter. You'll never have to set it again!
