As of today Firefox won't let me access SharePoint. Get '401 unauthorized' message

已張貼

In the past, I've been able to access our SharePoint hosted service without a problem.

Although I've not accessed SharePoint for a while, when I tried today (upgraded to Foxfire 30 in the meantime) I get the error message above.

Am able to access the site via Google Chrome.

SP hoster help desk tells me other Firefox users are having the same problem accessing their own (separate) SP servers.

They're using an old method of authentication which isn't considered secure any longer. The preference you just changed so that you can log into that website un-did a security fix that is new in Firefox 30. http://www.mozilla.org/en-US/firefox/30.0/releasenotes/

Tried all the suggestions, thank you. But the problem still remains. Simply cannot access SharePoint using Firefox. Chrome works and so does Safari - this is on a Mac. As far as I can see it has nothing to do with cookies or the cache, etc.

401 Unauthorized is a server error message related to an incorrect username / password.

That type of message might be related to Insecure NTLM (pre-NTLMv2) authentication being disabled in Firefox 30.

Type about:config in the URL bar and hit Enter. Accept the warning. Type NTLM in the Search bar at the top. Right-click network.negotiate-auth.allow-insecure-ntlm-v1 and select Toggle. Then close Firefox and restart.

See if you can access that SharePoint website without getting that 401 message.

Thank you very much for your advice. This has resolved the problem. I suspected it had something to do with Firefox 30, but I'd never have pinpointed the issue on my own! I don't no how best to spread the word because I'm sure there are others out there with the same problem.

Regards

I've notified the tech support people at the hosting company via a trouble ticket which was still open. I sent them most your not, above, with the links.

Thanks again.

Mozilla is making a choice to not use the local user's security profile and integrated Kerberos or NTLM authentication, as the other three major browsers do. This may be the right choice politically or for one technical reason or another, but ultimately, this affects users who use SharePoint, or maybe even Office 365. It makes one adopt Chrome quicker.

Also, not all Mac configurations need this change, and no Windows systems that we noticed need it. We have the same Mac OS level machines that do and others that do not need this NTLM v1 allowed configuration setting to connect to SharePoint - no idea why.

Thanks radascuta

It's helpful to get this kind of information and, for someone who is not technically trained, it suggests that with today's software 'secure' and 'simple' (to use) are probably both distant goals (wishful thinking?) and may not be compatible.

BTW I find that Chrome loads SharePoint pages very slowly and can't figure out why!
