Here's the situation: My firefox is not responding. I click on it and nothing happens, yet when I go to Finder to try and open/close it from there, it gives me the error message "The application Firefox is not open anymore," however, when I try and shut down my computer it won't let me because Firefox is open. My dashboard is signaling the program is running, so I'm not sure why it's not responding. If it helps, I was able to re-download and install a second version of Firefox which seems to be running fine. Attached is a screenshot of my dashboard, with the Firefox on the far right being the one that's operating.
