Block Specific Firefox Extensions

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?

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.
