After the update I can't seem to load WhatsApp Web. If I already logged in (using the QR code) it just doesn't load and eventually displays the 'connecting to WhatsApp' message which typically happens when the phone is offline. If I haven't logged in it will try to load the QR code for authentication and wait for that forever. The console shows the following:- Content Security Policy: Directive ‘child-src’ has been deprecated. Please use directive ‘worker-src’ to control workers, or directive ‘frame-src’ to control frames respectively. Firefox can’t establish a connection to the server at wss:// web.whatsapp.com/ws. app.fff9477f997fa1246faf.js:2:783554 Chromium on the same machine has no such issues.
