MeGaNeKoS/CR-Unblocker ? reverse-engineered prompt

Build me a Firefox extension that helps me open Crunchyroll when it’s region locked by routing only the Crunchyroll traffic through a US proxy, while keeping normal assets and media direct by default so the site still feels fast.

I want a simple settings page where I can turn diagnostics on and off, choose how much logging I see locally, and optionally enter my own SOCKS or HTTP proxy instead of using a shared one. Please keep the logs stored in the browser only, not sent anywhere else.

It should work on desktop Firefox and Firefox for Android, and I’d like a small dashboard or status page that makes it easy to see what’s being proxied and whether the service looks healthy. If you need to check current browser API details or Crunchyroll behavior online, go ahead and look them up.

Please build it cleanly so it can be packed and tested easily.
