Since a while ago, I cannot log in quitter.is with Firefox ESR in Debian but in the classic version. I can see the feed and all works as expected until I log in. After login, Qvitter interface causes a loop "cannot connect to server" and "Please log in to read the feed" (not exactly, the messages are in Spanish).
Even with all the addons disabled (https everywhere, Privacy badger, Self-destruct cookies and uBlock origin). While Tor-Browser works perfect, as expected.
Do you know why?
