Whatsapp web https://web.whatsapp.com/ does not work in firefox private browsing, as described here https://github.com/webcompat/web-bugs/issues/103595. The page attempts to load several times, then stops with a URL https://web.whatsapp.com/?logout_reason=0. It works in Firefox normal mode and in MS Edge, both private and normal mode. What I have done: Uninstalled all extensions Re-installed Firefox Refreshed Firefox Firefox 104.02 64 bit This is a known issue and has been around for half a year. Please fix it. I'm using Firefox mostly for privacy reasons, and not being able to use it in private mode is ironic and defeats the purpose. Looking forward to a solution. Thanks
