Garuda Linux has been hosting their own Firefox Sync server for a while now for
their FireDragon browser [1]:
defaultPref("identity.sync.tokenserver.uri", "https://ffsync.garudalinux.org/token/1.0/sync/1.5"); // --> FIREDRAGON CONFIG
(They seem to be running the older non-Rust sync server though. [2])[1] https://firedragon.garudalinux.org/
