syncstorage-rs

I don't see how your 2 questions are related to each other. > Do any of these forks have the ability to sync, either with Firefox or something self hosted? The Firefox Sync web service is provided by Mozilla but can be self hosted: https://github.com/mozilla-services/syncstorage-rs. That could also be used in forks. See e.g. https://librewolf.net/docs/faq/#can-i-use-firefox-sync-with-... . I don't understand what you mean by sync with Firefox. > Or are they all just basically reskins with a single toggle added or such? Hard to generalize, but definitely not all of them. see e.g. https://lwn.net/Articles/1012453/

Yes you can actually self-host both Firefox sync server [1] and use Firefox accounts (which also can be self-hosted [2] and someone put something simpler in docker image [3]). And those can be used even with Firefox itself not only the forks. [1] https://github.com/mozilla-services/syncstorage-rs [2] https://mozilla.github.io/ecosystem-platform/tutorials/devel...

Lucky us, you can do this today, because, of course, it is Mozilla, so it is open source: https://github.com/mozilla-services/syncstorage-rs

There's a MR open: https://github.com/mozilla-services/syncstorage-rs/issues/49...

The API docs are linked here: https://github.com/mozilla-services/syncstorage-rs?tab=readm...

In the documentation (https://github.com/mozilla-services/syncstorage-rs?tab=readm...), it looks like updating an about:config variable should be all you need to do: > In Firefox, go to about:config. Change identity.sync.tokenserver.uri to http://localhost:5000/1.0/sync/1.5. You'd need to update the URL to match your own, of course

In theory you could set up a simple sync server that implements the necessary endpoints and nothing more, nothing less. Guides like these run the official, Mozilla-maintained sync server, which is obviously based on serving millions of users rather than being a minimal implementation for someone in a home lab. One could fork https://github.com/mozilla-services/syncstorage-rs, take out the plumbing, and reimplement it all without a secondary database and the Google Cloud base architecture, I'm sure, but like with so many things, you'd first need to gather a group of people with enough interest and spare time to do the development.

Thank you, this is the only thing what slowed me down switching to Librewolf. Seems that MySQL and Spanner are the only supported DB-Engines by now, but there are efforts to support sqlite and Postgres[1]. I really hope these get merged soon, would make it much easier to backup your whole sync storage contained in one single sqlite file. However, a multiuser instance would probably be better stored via postgres due to better parallel update support. EDIT: After trying this out: How exactly do I force Firefox (Librewol) using the self-hosted URL? Is there an about:config setting? 1: https://github.com/mozilla-services/syncstorage-rs/issues/49...
