I am using Tor browser 7.5.6 (latest, 32 bits) on windows 10. I like to use Whatsapp on web. So I go to : https://web.whatsapp.com/

The site shows a QR code which I scan with my phone. And boom! I can access Whatsapp on my desktop via tor.

Now the problem is, for past 2 days, the QR code flashes for a while and then replaced by a timeout image. I googled and found one possible solution. That is disabling hardware acceleration. But I have intel-integrated-graphics, for which that option is not available. :-(

However, my Firefox 61.0.1 (64 bits) works absolutely fine with Whatsapp-web.

Can someone please throw more light on the situation ?

Thank you!

  1. In the adress bar in Tor enter: about:config
  2. Accept the risk
  3. Search for privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts
  4. Change the value from "true" to "false"
  5. Open WhatsApp web and if you are prompted to authorize the Input Canvas simply accept.
  6. Refresh the page
  7. Enjoy WhatsApp Web

Enter about:config into the address bar. You'll see a warning. Please be careful when making changes. Enter privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts into the search bar and double-click the entry. It should be set to false now. The setting was immediately changed and you can close the tab.

  • Could you extend your answer a bit? It is nice to know for other readers what you mean with about:config and where to put these values. – Jens Kubieziel Sep 7 '18 at 9:09
