Firefox / Chrome Setting Management

If you need to manage a configuration of a specific extension (eg. Add a website to the “Trusted Site” list on uBlock)

Firefox

Firefox’s extension config is put under a 3rdparty key that can be in a profile along all your other Firefox Settings

Profile:

<dict>
  <key>EnterprisePoliciesEnabled</key>
  <true />
  <key>3rdparty</key>
  <dict>
    <key>Extensions</key>
    <dict>
      <key>uBlock0@raymondhill.net</key>
      <dict>
        <key>toAdd</key>
        <dict>
          <key>trustedSiteDirectives</key>
          <array>
            <string>example.com</string>
            <string>example-two.com</string>
          </array>
        </dict>
      </dict>
    </dict>
  </dict>
  <key>PayloadDisplayName</key>
  <string>Firefox Config</string>
  <key>PayloadIdentifier</key>
  <string>some.identifier.here</string>
  <key>PayloadType</key>
  <string>org.mozilla.firefox</string>
  <key>PayloadUUID</key>
  <string>0CA00E46-3E4C-49CD-8DE3-40D08C20EB66</string>
  <key>PayloadVersion</key>
  <integer>1</integer>
</dict>

Chrome

Chrome’s extension configuration is a bit different in that it is actually a separate profile for different extensions. So you will create a profile called com.google.Chrome.EXTENSIONID.

Profile:

<dict>
    <key>toAdd</key>
    <dict>
      <key>trustedSiteDirectives</key>
      <array>
        <string>example.com</string>
        <string>example-two.com</string>
      </array>
    </dict>
    <key>PayloadDisplayName</key>
    <string>Chrome UBlock Config</string>
    <key>PayloadIdentifier</key>
    <string>some.identifier.here</string>
    <key>PayloadType</key>
    <string>com.google.Chrome.extensions.cjpalhdlnbpafiamejdnhcphjbkeiagm</string>
    <key>PayloadUUID</key>
    <string>0C06F283-26C7-4BDA-86E9-D6506F025B30</string>
    <key>PayloadVersion</key>
    <integer>1</integer>
</dict>
