1. build a #docker image from https://github.com/mozilla-services/syncserver
2. #deploy it somewhere
3. configure identity.sync.tokenserver.uri in #about:config to point to your new location
4. login at `about:preferences#sync` (you still need a #mozilla account, unless you also run a private account server)
5. sync and check about:sync-log for #error|s
@martin I thought, Mozilla stopped syncing to custom servers. I used weave in the past. Does this work again? How about Firefox mobile? At the moment I sync to Nextcloud bookmarks with the Floccus addon in Firefox. Works pretty good.
@mase it is supposed to work on #android, but i can't confirm that...
i'm using #orfox and #fossbrowser, which however do not support sync.
there is no pure #firefox in the @fdroidorg repository (and #google #play #store is not an option). just tried #icecat but cannot sign in to sync (probably related to https://savannah.gnu.org/bugs/?50960)
mstdn.binfalse.de is one server in the network
