CORS Unbound szerző: yobukodori

CORS Unbound is a Firefox extension that bypasses CORS restrictions and rewrites HTTP request/response headers directly inside the browser.
It is designed for local development, prototyping, automation, scraping, and advanced debugging — all without running a server.

Features

Automatic CORS Bypass
Injects the appropriate Access-Control-* headers into responses based on the browser’s own CORS request headers.

Header Rewriting
Add, modify, or remove request and response headers using a rule-based UI.

Rule System
Each rule defines:

• Origin URLs (the page making the request)
• Target URLs (the request destination)
• Header Actions (set/remove)
• Resource Types (xmlhttprequest, sub_frame, script, image, websocket, etc.)
