Today I was trying to access WhatsApp Web in Firefox and then, this screen was displayed, with no messages, nor a QR code to scan:

It sounded strange, because I never had this issue. Then, I accessed some sites that identify the browser. Some said I'm using Chrome 53, and one was unable to identify my browser.

I'm 70% sure that I can't access WhatsApp Web due to this browser detecting issue. Is there something I can do about this? I'm using the most recent Firefox version provided by the Ubuntu software and Ubuntu 14.04.

  • It works in mine.

    You may be using some addon that changes the user agent or something.

  • @CelticWarrior Isn't this more likely to be a certificate problem?

What worked for me on Ubuntu 17.04:

  • Removing web.whatsapp.com Data under Preferences > Advanced > Network > Offline Web Content and User Data

What did not work:


I thought at first it might have something to do with running a private session, but testing indicates this is not the case. Since your accessing the site via https (Secure Hyper Text Transport Protocol) Updating your certificates with sudo update-ca-certificates should do the trick.
