Resolve Firefox access (localhost) local Web site prompt for username password

VS in the debugger when the browser is always prompted to enter the user name and password, but my program does not have a login interface, finally found a solution, as follows:

1. In the Firefox address bar, type: about:config

2. Then type: NTLM in the search text box

3. Locate and double-click Network.automatic-ntlm-auth.trusted-uris,

4. Enter localhost in the input value

5. Then restart Firefox browser.
