Privacy Header door David Sint

I used to use ModHeader, but after changes that made me uncomfortable, I realized I could just vibe-code a better alternative with no restrictions and no risk of malware or ads. This is that alternative. This was created for my personal use, I take no responsibility for your usage.

Features:
1. Profiles
2. Custom URL regex per profile for when to apply modifications
3. Unlimited number of header manipulations
4. Auto-merges duplicate header keys
5. No ads, no back-doors, open-sourced
