Hi Team, I have one website portal where we need to enter username and password to access the portal. when i access website from different browsers like Google Chrome, IE and Microsoft Edge, its automatically authenticating my windows login credentials. But when i am trying to access the same website in firefox , its not authenticating. i have to enter my username and password and than portal up for me and working. I have done some basic troubleshooting step but nothing is working for me. steps: network.automatic-ntlm-auth.allow-proxies True network.negotiate-auth.allow-proxies True network.automatic-ntlm-auth.trusted-uris, double click on this and i have entered my website url. closed Firefox and open again still same issues. I have also added my website under Exceptions list in Security options, still not working
