Recently, I've run into logging in on at least two websites where I have two-factor authentication set up. I'll click the sign in button, and rather than advancing to ask for my authentication code, I get stuck in an endless loading loop and am unable to do anything. Is there anything I can do to fix this? I have already tried clearing cache and cookies and restarting in safe mode. This issue only happens to me on desktop. The mobile version of firefox still lets me log in, but I prefer to use desktop.
