Mozilla seems to keep this very quiet, but from what I can see in this documentation it's extremely easy to implement your own sync server, with only one flag in about:config needing to be changed and minimal build dependencies. The harder aspect comes with the Firefox accounts server, as that requires a bit more configuration and deployment. I would be very interested in seeing someone build a docker-composer setup for this, such that it can be automatically deployed for those who don't have the time/skills to set it up.
