I use Firefox (LibreWolf with Mozilla sync) on multiple devices. To have my tabs, extensions and history easy available I use Mozilla for syncing that data.
Would it be possible to just use a generic sync service like rsync or something, to sync the profile folders and every file in it?
Or would that break or corrupt data?
An article was posted recently that you can host the Firefox sync server yourself. Supposedly a bit fiddly, but doable. If you’re considering self hosting something anyway, might as well be the right tool for the job.
Hope these help:
Yeah I justed edited my answer, because OP needs to sync everything (Tabs, History, extensions…)

Is the newer version rewritten in rust ! And probably OPs best bet :)
