I want to access a webpage on a non-standard port.
On desktop, I can override port bans for Chromium-based browsers and Firefox.
On Android, I FUCKING CAN'T, FIREFOX' CONFIG VALUE USED ON DESKTOP DOESN'T DO ANYTHING ON ANDROID, ANY OTHER BROWSER ALSO DOESN'T HAVE ANY CONFIG FOR THIS, AAAAAAAAAAAAAAAAAAAAAAAAAA

Site's on port 21 because that's one of my school firewall's few allowed outbound ports, and I couldn't use 80/443 since a webpage is already running there.
