Open Report Manager in Firefox and Solve Authentication Request

When ever you try to open report manager in Firefox, (assuming you open Firefox as administrator), Firefox will prompted authentication for username and password. No matter how much you insert an username and password, it keeps on prompting. It's frustrating. I know.

Here's the way. 

1- Go to the url and type about:config. 

2- Search for network.automatic-ntlm-auth.trusted-uris. Double click.

3- Put your value string. Value string is your domain name. 

(Example: http://os-fatimah/reports. so your value will be os-fatimah)
