1. Overview

Most modern versions of Firefox are generally compatible with Moonshot.

On Linux, Firefox is integrated with the GSS-API and uses the Moonshot Identity Selector.

macOS support is currently in development, you must currently use the .gss_eap_id file in your home directory. See the macOS Compatibility List for more details.

On Windows, Firefox is integrated with the Windows Security Support Provider Interface (SSPI) and requires the Moonshot SSP.

By default, Firefox disables the Negotiate options in their configuration for security reasons.

To enable these, follow the below steps:

Open a new tab in the browser
Into the address field type about:config and confirm the subsequent warning:
Into the Preferences search bar type negotiate to show the Negotiate options
Adjust the network.negotiate-auth.trusted-uris and/or network.negotiate-auth.delegation-uris options with the hosts or realms that you would like to enable Negotiate authentication for:
On versions of macOS later than El Capitan, you must also sidestep the Apple sandboxing functionality:
1. Create a soft link to the existing Kerberos library:
```
sudo ln -s /System/Library/Frameworks/Kerberos.framework/Kerberos /usr/local/lib/libgssapi_krb5.dylib
```
2. Adjust the network.negotiate-auth.gsslib option with the location of the 'new' library you set in the step above:
Restart your browser.
