> I understood that Fenix won't support Firefox Sync
Based on my user experience Fenix (Firefox Preview) supports Firefox Sync in terms of bookmarks. I believe history and other data is also synchronized, but I haven't had occasion to test it thoroughly. In my opinion claim that "Fenix won't support Firefox Sync" is a bit too far [0]. I noticed the login/password sync feature has not been implemented yet [1]. I suppose it will might materialize soon, because lack of it could be a huge mistake in terms of usability.
