Bluecoat Firefox authentication Pop-Up’s
To solve the problem do the following:
Type in Firefox Browser – about:config
Find value “network.automatic-ntlm-auth.trusted-uris” and add bluecoat host name
For https authentication is recommended to create Virtual URL and add a different port (not 443 ) https://bluecoatHostName:444
Also check DNS resolution of bluecoat applience ( probably you will need to add it manualy to your DNS serve
