I was updating Firefox on my on my computer, Mac OS 10.11.6( I know, I know…). Now The current version of FF won’t run and I am unable to upgrade the operating system because it so old. Is there a way to figure out which version of FF I had? Its slightly overwhelming to look at the choices of older versions to download. Any help is appreciated. Been a FF supporter forever and love it!
