Firefox for Android (“Daylight”, versions 79 and later) does support using a non-Mozilla-hosted Sync server. Before logging in, go to App Menu > Settings > About Firefox and click the logo 5 times. You should see a “debug menu enabled” notification. Go back to the main menu and you will see two options for a custom account server and a custom Sync server. Set the Sync server to the URL given above and then log in.
To configure Android Firefox 44 up to 78 to talk to your new Sync server, just set the “identity.sync.tokenserver.uri” exactly as above before signing in to Mozilla accounts and Sync on your Android device.
Important: after creating the Android account, changes to “identity.sync.tokenserver.uri” will be ignored. (If you need to change the URI, delete the Android account using the Settings > Sync > Disconnect… menu item, update the pref, and sign in again.) Non-default TokenServer URLs are displayed in the Settings > Sync panel in Firefox for Android, so you should be able to verify your URL there.

the /token/ prefix is experimentally wrong.
This commit introduces a new NixOS module `networking.getaddrinfo` to allow
declarative configuration of `/etc/gai.conf`, which controls address
selection behavior for `getaddrinfo(3)` as defined in RFC 3484 and
RFC 6724.
vmalert only supports a single datasource for querying metrics and
managing alerts. Because of that, we need two instances to manage alerts
for both VictoriaLogs and VictoriaMetrics.
This is strongly inspired by the change made to Redis, i.e. a new
`instances` option was introduced with each option inside it.
With `mkRenamedOptionModule` it's ensured that existing configurations
still evaluate to the same result.
