I have an iMac. Operating system is High Sierra 10.13.6. Firefox was running slowly today and a pop up window came up on the bottom of my screen and gave me the option of "refreshing" Firefox. I hit the refresh button, and it was taking FOREVER to refresh Firefox, so I clicked out of it (the little red button) mid-refresh. Ever since then, when I try to open Firefox, I get a message stating that Firefox cannot be opened because my profile is missing or deleted. Shortly after this happened, a folder appeared on my desktop titled "Old Firefox Data" which contains about 60 items. I did not create this folder. I have tried uninstalling and reinstalling Firefox. I have also tried starting my iMac in safe mode, then restarting in regular mode. Was on the phone with Apple Tech Support for over an hour and they were unable to help. They are aware of the "Old Firefox Data" folder but they didn't know what to do with it. I am not tech or computer savvy. Other people have posted this exact question before, and answers have been provided, however I don't understand the answers or the instructions that supposedly solve this problem. This is why I'm asking this question again. I am hoping someone can help and provide a simplified answer or simplified instructions to solve this problem. Thank you.
