Yo, I feel you. Proxy settings in Mozilla can be a pain. Have you tried resetting Firefox to default settings? Sometimes custom configs mess things up.
Also, make sure your proxy server is actually working. You can test it using a site like proxycheck.io. If the server’s down, no amount of tweaking will help lol.
