Can't get Firefox debugger to work in Visual Studio Code for macOS

I installed the Firefox Debugger but when I did Start Debugging and choose Firefox from the choices given, I got this error:

Couldn’t find the Firefox executable. Please specify the path in your launch configuration.
Here’s the launch configuration that was made (launch.json):
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": “0.2.0”,
“configurations”: [
{
“name”: “Launch index.html”,
“type”: “firefox”,
“request”: “launch”,
“reAttach”: true,
“file”: “${workspaceFolder}/index.html”
},
{
“name”: “Launch localhost”,
“type”: “firefox”,
“request”: “launch”,
“reAttach”: true,
“url”: “http://localhost/index.html”,
“webRoot”: “${workspaceFolder}”
},
{
“name”: “Attach”,
“type”: “firefox”,
“request”: “attach”
},
{
“name”: “Launch addon”,
“type”: “firefox”,
“request”: “launch”,
“reAttach”: true,
“addonType”: “addonSdk”,
“addonPath”: “${workspaceFolder}”
}
]
}

I have no idea how to do that nor do I understand why I would need to. Why doesn’t it just call the app through macOS?

Thanks in advance

Perhaps an issue with the extension

It says that firefoxExecutable is the name of the property, perhaps /Applications/Firefox.app/Contents/MacOS/firefox-bin is the correct value?
