FireFox 30, can't access internal websites. It gives us 401 - Unauthorized: Access is denied due to invalid credentials.

Posted

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?
