Here your ass on your elbow like you asked

Chrome, Edge, Tor, Brave, Opera, Opera GX, Yandex, Vivaldi, Chromium, Waterfox, Epic, Comodo, Slimjet, Coc Coc, Maxthon, 360 Browser, Falkon, and two lesser-known variants.

Ok as is Jellyfin will only work on your home network, Tailscale make a localise VPN between your server and an other device.
