title: Setting the browser language in Cypress
body: <p>Is it possible to tell Cypress to launch Chrome with a certain language (e.g. German) as I have an application which I need to test in multiple languages. I can't see this detailed anywhere in the documentation which suggests it is not possible at present.</p>
  
  <p>I have tried adding the <code>--lang</code> argument when Chrome is launched but this does not seem to have any effect and Chrome still uses English. See the <code>pluginsFile</code> code below.</p>
  
  <pre><code>module.exports = (on, config) =&gt; {
    on('before:browser:launch', (browser = {}, args) =&gt; {
      if (browser.name === 'chrome') {
        args.push('--lang=de')
        return args
      }
    })
  }
  </code></pre>
  
  <p>I have also tried <code>--lang=de-DE</code> which also did not work.</p>
