nope. FFx has an issue with NY Times. Any other browser works. And any other site works with FFx.

Check that the login is stored in the Password Manager. Type about:preferences#security<enter> in the address bar. Look under Logins,

Note: For Firefox v56+ its; about:preferences#privacy Look under Forms & Passwords Or type about:logins<enter> in the address box. +++++++++++++++++++++++++++++++ Turn on Remember Logins. To check the passwords you have listed, press Saved Logins.

Press the Exceptions button and see what's inside.

login is saved. remember is on. exceptions is empty.

I've just discovered this is the case with citibank as well.

You can create a cookie allow exception in "Settings -> Privacy & Security" for the top level domain.

I have done that with both NYTimes and citi. Both cannot be logged into w/FFx 93.

seems v94 has fixed the issue with citi. but NY times is still broken.
