This is a browser extension and server which I use to store and distribute up-to-date login cookies necessary for some of my projects. Currently supports retrieving cookies and user IDs from YouTube, Bandcamp, and SoundCloud.

1. Download the extension here and install it in your browser(s). Since the extension is unsigned (for now) you must follow some extra steps:
   1. For Firefox, you must be running Firefox Developer Edition or Nightly and set xpinstall.signatures.required to false.
   2. For Chrome, you must go to chrome:https://extensions and enable Developer mode.
2. Run the cookie-relay server so that it is accessible from your browser(s) which you installed the extension in. It must be accessible via HTTPS. See the example docker-compose file below for how I do this with Tailscale.
3. Configure the browser extension settings so that the API url points to the cookie-relay server, and the API key matches the API key used by the server.

• Replace <YOUR TAILNET NAME> with your Tailnet name (see the docs).
• Replace <RANDOM API KEY> with a random string of characters. This is the API key you will set the browser extension to use.
