How do you get Firefox to ask for proxy username password in a pop up window?

Previously, about a month ago a pop up message would appear when I would connect to my University's wired network proxy to ask me for my password. In Chormium Browser the following message pops up when I log in http://tinypic.com/r/i77lhi/8. A similar thing used to happen in Firefox, but doesn't anymore. I know it is not my proxy settings that are incorrect as I have double checked them and it is only in Firefox that it fails. I have Firefox set to use system proxy settings and this is the setting that is dictated by the University. It is very possible that I changed a setting while tinkering that prevents such message boxes from appearing or uses an old username and password automatically, but I haven't been able to find anything like this.

Help would be greatly appreciated! I am completely stuck on this. Thanks Jason

Maybe you have this issue:

In Firefox 30 and later NTLMv1 auth has been disabled, NTLM support on non-Windows platforms is now deprecated

In Firefox 31 support for NTLMv1 auth has been restored for secure connections only (Bug 1023748).

  • network.negotiate-auth.allow-insecure-ntlm-v1 = false
  • network.negotiate-auth.allow-insecure-ntlm-v1-https = true

Bug 1023748 - Allow NTLMv1 over SSL/TLS, or intranet access is broken on Firefox 30 for non-Windows platforms
