Firefox will not run on my MacBook Pro, tried MacOS Sierra and MacOS Mojave.
I double click the Firefox application in the Applications folder. The icon bounces, but it doesn't complete opening the application. There is no pop up dialog window to explain why.

Have you tried uninstalling Firefox and reinstalling it?
Yes, many times. This is occurring on more than one computer.
