Policy support can be implemented using a JSON file called policies.json. Unlike controlling Firefox with using Group Policy, the policies.json is cross-platform compatible, making it preferred method for enterprise environments that have workstations running various operating systems.
To implement this policy support, a policies.json file needs to be created. On Windows, create a directory called distribution where the EXE is located and place the file there. On Mac, the file goes into Firefox.app/Contents/Resources/distribution. On Linux, the file goes into firefox/distribution, where firefox is the installation directory for Firefox, which varies by distribution - or you can specify system-wide policy by placing the file in /etc/firefox/policies.
The policies.json file looks like this:
{
"policies": {
"BlockAboutConfig": true
}
}
In this example, we are setting the BlockAboutConfig policy to true, which means that the user will not have access to the about:config page.
The latest information about our policies is available at https://mozilla.github.io/policy-templates/ or on the about:policies#documentation page in Firefox.
