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 ?
