Firefox can't be opened because it was not downloaded from the Mac App store

Hi,

Any idea how I can fix this issue? https://twitter.com/DanielGrubb8/status/980524377929342977

I am not an OS X user so it’s hard for me to do support to OS X users if anybody else can pick this up, it would be great

Thank you!
