Firefox Web Browser Login issue with Office 365
I have user who cannot login to O365 using Firefox. It has been working for months now but all of a sudden it won’t let him login. He can login using Google Chrome without an issue. I can see it trying to login but it goes back to login screen. Have un-installed and re-installed Firefox two times and it does the same thing. Am I missing something somewhere, cookie, cache etc.,. ?
System Specs... Windows 8.1 64bit Firefox 82.0.2 64bit
