Run Firefox in headless mode using Protractor config

Question

I have this in my Protractor config:

  multiCapabilities: [

    {
      browserName: 'firefox',
      firefoxOptions: {
        args: ['-headless']
      },
      'moz:firefoxOptions': {
        args: ['-headless']
      }
    }

  ]

unfortunately, when I launch Protractor, Firefox still runs in a headful mode. How to the heck do I tell Firefox to as headless?

I know that at the command line, the -headless option should work so.

Answer 1

I guess, you are missing extra hypen (-) in your config.

multiCapabilities: [
{
  browserName: 'firefox',
  firefoxOptions: {
    args: ['--headless']
  },
  'moz:firefoxOptions': {
    args: [ '--headless' ]
  }
}
]

Also your browser version should be greater than 56.
