Watir won't open Firefox

I'm trying to use Watir with Firefox:

browser = Watir::Browser.new :firefox, options: {prefs: {'intl'=> {'accept_languages'=> 'en-US'}}}

But keep getting this error:

Preference values not all string or integer or boolean (Selenium::WebDriver::Error::InvalidArgumentError)

I've found that the issue is likely caused by Geckodriver so I've installed geckodriver-bin (0.28.0) but still no luck.

Any tips?

Looks like you need to use intl.accept_languages:

browser = Watir::Browser.new :firefox, options: {prefs: {'intl.accept_languages' => 'en-US'}}
