Unable to log in to ADFS using FireFox 30.0

I try to login to ADFS using Firefox 30.0. SP sends auth request. ADFS shows error:

Server Error 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

Other browsers and other versions of firefox are working.

Firefox disabled NTLMv1 authentication by security reasons since version 30.0. It recommends to upgrade NTLM to version 2. But NTLMv2 is supported only on Windows platform. Read https://bugzilla.mozilla.org/show_bug.cgi?id=973640

Workarounds:

1) To login using ADFS with NTLMv1 and FF 30 and higher you should to configure FF. Open settings page about:config. Set network.negotiate-auth.allow-insecure-ntlm-v1 = true.

2) To don't use NTLMv1 in ADFS you can change the local authentication type to "Forms-based authentication".
