When reading a file via javascript readAsArrayBuffer and file is not readable, Firefox does not call "onerror" handler and instead stops the javascript with error: NS_ERROR_FILE_ACCESS_DENIED

blob = file.slice(0,1); var reader = new FileReader; reader.onerror = function(e) { 

  // this is called under Chrome, but not under Firefox
  console.log('reader.onerror');

} reader.readAsArrayBuffer(blob); // this stops with NS_ERROR_FILE_ACCESS_DENIED

According to FileAPI it should: https://developer.mozilla.org/en-US/docs/Web/API/FileReader
