Update: I solved my problem.
I got everything working by using this repo, but also by not using LibreWolf - looks like either I'm missing something about its setup, or syncstorage-rs (firefox sync) doesn't handle it well: I noticed that when using it I would get "ua.os.ver":"UNKNOWN" in the logs, so maybe it's related.
I'm trying to host my Firefox Sync server. I got it running using docker and with instructions from this github repo. Everything looks fine, I think... I can reach the host and I can reach the __heartbeat__ endpoint, getting this response: {"version":"0.13.6","quota":{"enabled":false,"size":0},"database":"Ok","status":"Ok"}, but nothing seems to sync!
I set it up first on my LibreWolf instance and checking the docker container logs look like this:

I set my sync settings to have add-ons, bookmarks and history synced. I installed some add-ons, saved some bookmarks and tried to sync with a new browser profile, then with Firefox on Fedora and Mull on Android, but nothing seems to be moving.
Any idea what more to do to troubleshoot this?
FreshRSS has some too: https://freshrss.github.io/FreshRSS/en/users/08_sharing_services.html
Wallabag is nice - it's making an archive of the page you're saving and I think you can export it as pdf/epub to read it on any device.
