title: Highcharts not displaying in Firefox
body: <p>I am using the following JavaScript Code to create a Highchart from a local csv file. This works correctly in Safari and Chrome (need to enable <code>--allow-file-access-from-files</code> for it to work in Chrome), however it does not work for Firefox for some reason. I have tried changing the value of <code>security.fileurl.strict_origin_policy</code> to false but that doesn't change the error or display the charts.</p>
  
  <p>I get a JS "syntax error" for the csv file for ':1:1' which I assume is line 1 column 1. I don't understand why it works for 2 browsers and not for Firefox. I imagine it is something similar to Chrome where I have to enable access to local files but besides changing the <code>about:config</code> I'm not sure how to achieve this.</p>
  
  <p>Any explanations or suggestions are appreciated.</p>
  
  <pre><code> $.get(data, function(csv) {
        $('#container').highcharts({
          chart: {
            zoomType: 'x',
            type: 'column',
          },
          data: {
            csv: csv,
            lineDelimiter: "\n",
          },
          title: {
                text: 'CSV file data'
            },
          yAxis: {
              title: {
                  text: 'Bytes'
              }
          }
        }); 
      });
  </code></pre>
