- I have Firefox on several machines, and on each one I have a rigamarole of setting the settings the way I like them, installing a list of addons, etc. I know I can sync these things between machines, but to do so, I must "log in" to "Firefox Sync". I don't want the web browser vendor having my data. I don't trust that. I don't care if they say they encrypted it or whatever.

Is there a way to "self-host" firefox sync? If so, is it turnkey or will I be custom python scripts or something?
