URL: https://web.whatsapp.com/

Browser / Version: Firefox 99.0
Operating System: Windows 10
Tested Another Browser: Yes Edge

Problem type: Site is not usable
Description: Page not loading correctly
Steps to Reproduce:
Whenever I try to login to whatsapp using the whatsapp web feature displays a blank screen with no QR code to scan.
This website keeps loading for more than a couple of seconds and only the icon and line "Whatsapp End to end encrypted" is displayed.

This is happening from past 5 days.

Below is the url link
https://web.whatsapp.com/?logout_reason=0

I can reproduce by following these steps:

1. Start Firefox by clicking on the desktop icon
2. Press Cmd+N (or Ctrl+N for Windows users) to open a new browser window
3. Paste https://web.whatsapp.com in the address bar and press Enter

Expected results: How to use whatsappweb and the QR code to scan.
Actual results: website keeps loading for more than a couple of seconds and only the icon and line "Whatsapp End to end encrypted" is displayed.

Since using a permanent private browsing mode, cookies and site data will always be cleared when Firefox is closed.
