Hi there,

We have Firefox 30 on one of our servers and it will not let us access any of our internal sites. It gives a message:

401 - Unauthorized: Access is denied due to invalid credentials.

It doesn't even prompt for credentails. Other browsers work fine. I tried a solution from a previous post but it didn't work: "you can try to enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named network.negotiate-auth.allow-insecure-ntlm-v1. double-click it and change its value to true."

What else could be causing this issue?

Thanks, Rhonda

It should work if you have network.negotiate-auth.allow-insecure-ntlm-v1 set to true, but there is also network.negotiate-auth.allow-insecure-ntlm-v1-https that is by default true.

However that may not be the only issue. What version where you using before? Are you using fqdn?
