We normally have an option in IE to add any site to a trusted intranet zone and we can auto-login to that site with our domain credentials.
But in Mozilla we don’t have any option directly on UI for that. I even didn’t know whether it was possible or not.
We can configure Mozilla options by following the below mentioned steps.
Step 1: Open Mozilla and type about:config in the address bar.
Step 2: All the configurations would be listed.
Step 3: Now, type network.automatic in the search text box.
Step 4: Many options would be listed. Double click on network.automatic-ntlm-auth.trusted-uris option and add multiple domain urls separated by comma.
Step 5: Now try to logon to any intranet site, you would be able to browse it without login prompt.
