Fixing the localhost authentication problem in FireFox

for some time I had a strange problem; I could load sites from http://localhost in MSIE, but whenever I tried FireFox, it asked me for an user name and password. I’ve tried it all but I couldn’t authenticate.
If you happen to have the same problem, here’s a quick and simple workaround:

  1. In Firefox type about:config in the addressbar
  2. Find the preference named network.automatic-ntlm-auth.trusted-uris
  3. Doubleclick and type localhost
  4. Enter and you’re done

  1. The above solution did not work for me as it had something got to do with proxy in my case.
    The following worked for me:
    Set proxy settings to automatic in firefox. Options>Advanced>Network> Settings>Auto detect proxy settings.

  2. None of the above fixed it for me.
    I had to change “Tell sites that I do not want to be tracked” to “Do not tell sites anything about my tracking preferences” and it was fixed immediately. What an odd fix.

  3. It had been bugging me for a while, and I can\’t believe how easy it is to actually fix it.]]>
