Firefox 81.0.1 doesn't open some Twitter windows, doesn't access Proton Mail, doesn't allow Gmail to receive mail.
I can open my Gmail and Protonmail on Edge and in my Android device, but not in Firefox 81.0.1. on Windows 10 Desktop. I can open Twitter 'groups' and Home and Notifications, but not individual Profiles and Searches.
