Add the ability to proxy traffic only for selected domains. Now the browser only has "No proxy for", we need the opposite function "use proxy only for". I want to be able to fully use Firefox proxy together with the CloudFlare WARP client to redirect traffic only for selected sites. In CloudFlare WARP, you can register domains for split tunneling, but this doesn't work because the browser uses DoH (DNS over HTTPS) and ECH (Encrypted Client Hello) - I do not want to disable these technologies. The only thing left is to use the local proxy server function in CloudFlare WARP - in this mode, their client works as a local proxy server (receives traffic from other programs configured for a local proxy) and sends it to their VPN.
