Hi, I have the same problem, but disabling Account Hub doesn't change the result. The Account Hub box is unchecked, but when I try > New Account > Email, I still get the "Authentication failed" error.

I have tried this with my outlook, and gmail accounts. I have tried restarting the computer, and various other fixes online.

Thank. you all set done by preivios reply.

That option doesn't work any more; the Hub is now the default for new accounts. Piggybacking isn't polite netiquette, not to mention the fact that very few will see it here. Please post a new issue of your own at https://support.mozilla.org/en-US/questions/new/firefox/form.

If you exactly like the first reply it will work and had to restart my Imac as well.Hope this helps maybe thunderrbird (firefox) will fix this issue in next update.
