What happens if you type about:profile directly into a Firefox browser window?Ĭan you email screenshots directly to our support email address and I will take a look. It sounds like your Mac is just running the Firefox program (or binary file / executable), and not seeing the -profilemanager part. firefox-bin –profilemanager, there should be a single space followed by a dash and immediately afterwards profilemanager.

Are you referring to the section on page 29, entering commands into a Terminal prompt? Ensure you type the commands exactly as shown!
