Unable to log into openai.com

I'm using LibreWolf browser (based on Firefox).
After trying to log in, I get redirected to the https://chat.openai.com/auth/login page without any additional messages. No error messages, nothing.
I've tried clearing cookies, using private window. Doesn't help. Then I tried just Firefox and it didn't work. Then I tried Microsoft Edge and it worked.
Seems like there are issues with Firefox. Do you know what it might be?
