Is there a way to configure Firefox 29 to work with an self-hosted fsyncms-Server by editing e.g. some settings in about:config?

I can use my server by installing an older version of Firefox and configuring sync there. After sync is configured, I can upgrade to FF 29 and it works perfectly. So where are these settings saved?

Thanks in advance, efzwo

In about:config add services.sync.username string and type some value

  • I think the OP wanted to know how to change the server for Sync, not the username.
