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?
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 :)
Will check this out, thanks!
