If it can't attach to the server, then it can't execute anything.
So let's focus on getting it to attach.

1. Can you try :JupyniumStartAndAttachToServerInTerminal and see if it's the same message?
2. Does your firefox work with command firefox?
3. Does your firefox work with Selenium with this simple code?

   from selenium import webdriver
   driver = webdriver.Firefox()
   driver.get("https://www.selenium.dev/selenium/web/web-form.html")
