There's this good discussion here regarding the question: https://askubuntu.com/questions/1378056/ubuntu-20-04-3-problems-running-firefox-from-terminal

I'll quote some points from the answers there to answer your question:

1. Why do you get this error? It's because you don't have any other firefox windows launched

2. How to exit? There are several ways:

   1. Press Ctrl+C inside your console to terminate the process
   2. Open a new terminal window, and run the command sudo ps -aux | grep -i "firefox", take the process ID of the first entry and kill it using the command sudo kill -9 PROCESS_ID
   3. You could use a tool such as disown or nohup to run the process in the background and keep using the same terminal window. You can learn more about the differences between these tools here (https://unix.stackexchange.com/questions/3886/difference-between-nohup-disown-and)
