I do not think Whatsapp has made a version for the Firefox OS yet.

There are some options though. https://marketplace.firefox.com/search?q=Whatsapp

See http://mzl.la/1BAVl8N for alternatives.

But I don't like these apps. I need whatsapp. ConnectA2 is unable to connect to my whatsapp account.

Be careful using these type of whatsapp apps from Maket. You can get banned from whatsapp network forever.

@llumex03 Can confirm, I experienced this once. Still using OpenWapp with another number though...

This is what WhatsApp support told me when I asked: http://pastebin.com/uesAGhw8

If you are Firefox OS users and cannot buy another supported whatsapp phone, i recommend you Telegram.

Which is officialy supported
