so many time we are facing this problem when we are using FF(Mozilla Firefox) . issue is we need to enter userid and password when we are using localhost,on IE(Internet Explorer) it has some internal ability to window user for Authentication ,but on firefix its not but don’t worry, you’ll have to make a quick some configuration change.

follow the steps :

1) Open up Firefox and type in about:config as the url

2) In the Filter Type in ntlm

3) Double click “network.automatic-ntlm-auth.trusted-uris” and type in localhost and hit enter

4) thats it ,

hope it will help you, if you like this trick show your appreciation on reply
