mobileEmulation capabilities for Firefox in webdriver IO

Question

I am trying to write end to end test cases for mobile web browsers. So I am setting the configuration for google chrome as below and it runs fine.

{
  browserName: 'chrome',
  'goog:chromeOptions': {
    mobileEmulation: { deviceName: 'Apple iPhone 6' },
  }

But I am not sure from where 'goog:chromeOptions' is taken. I tried searching wdio docs and couldn't find any. I just got this from one of the blog that we need to pass key as "goog:chromeOptions"

Similarly I also need to run for Firefox and safari browsers. So I am not sure what key/hash we need to pass for firefox for mobile emulation.

I am trying to learn WDIO by practising simple exercises.
