Firefox will not open saying it can't find the profile. There is a profile in the Application Support folder and old ones on the desktop. I followed the directions to access the profile manager through Terminal, but it didn't work. This Firefox Application is one I restored from Time Machine. I got into this problem when I tried to update Firefox. My MacOS system does not meet the requirements to install the latest Firefox. Apparently, my former Firefox got uninstalled in the effort to install the latest version.
