Block Specific Firefox Extensions

[stevefitz]

I'm trying to block a specific extension in Firefox. It works if I block all extension, but not when I reference the specific extension ID. I confirmed that the extension ID is correct. Any suggestions?

try with the install_source Key and URL of the extension 

  <key>ExtensionSettings</key>
  <dict>
    <key>*</key>
    <dict>
      <key>blocked_install_message</key>
      <string>Custom error message.</string>
      <key>install_sources</key>
      <array>
        <string>"https://yourwebsite.com/*"</string>
      </array>
     <dict>

Thanks. It works if I block all extensions I'm just not able to block a specific extension and allow other extensions to be installed.
