allow cors - access-control-allow-origin

allow cors - access-control-allow-origin is a flat, lightweight developer utility to bypass cors, strip security headers, and configure custom redirects during local api testing. it runs 100% locally in your browser using native manifest v3 declarative rules, requiring zero idle cpu overhead and providing full compatibility with modern security standards. key features: * cors bypass: dynamically modifies response headers to permit cross-origin api queries. * credentials unblock: resolves browser wildcard blocks by matching the active tab's origin and injecting access-control-allow-credentials: true. * auto-disable alarm: automatically switches off the extension after 1, 10, 30, or 60 minutes using native background chrome alarms to prevent security leaks. * redirect mapping: redirects remote api patterns or javascript files (e.g. *zoologyfibre*/*.js*) to local mock routes (e.g. http://localhost:3000/mock.js). * headers stripping: removes content-security-policy (csp, x-webkit-csp, x-content-security-policy) and x-frame-options (frame-options) headers to test frames and embedded resources. * rules mode: choose between blocklist (allow all except exclusions) and allowlist (allow only custom domains) modes. * request counter: tracks intercepted and modified calls in real-time. all overrides run locally. no data is tracked or collected.
