HeaderNinja Asif Iqbal מאת

HeaderNinja adds or overrides HTTP request headers on outgoing requests.

• Add any header name + value from a simple toolbar popup
• Optional per-rule URL filter — target one site or leave blank for all
• One master switch to enable/disable every rule at once
• Rules are saved locally and applied instantly

Built on Manifest V3 declarativeNetRequest. No tracking, no remote code, no data collection — everything stays in your browser. Handy for API testing, auth tokens, custom user-agents, and debugging.
