You can log in to a Mozilla account in both the desktop and mobile browsers and sync everything that way. No Google needed!

Here in the Netherlands no one uses SMS, purely Whatsapp. So removing this functionality, though often complained about by people presumably from the US, did not hurt functionality at all here. I also like the features like Stories, it's a direct competition with Instagram/Snapchat, though just like Whatsapp Stories, barely anyone will use it.
