window.requestFileSystem not working

Following is the code to generate a csv file using any data from HTML page. In my case, I hvae a variable history in which I have data collected from a HTML table.

By this code, I can download the generated csv file in my computer. this code is working fine in Google Chrome but not in Firefox. I need to run it in firefox too.

This code is from HTML5

You can try this code here

window.webkitRequestFileSystem(window.TEMPORARY, 1024*1024, function(fs) {
        fs.root.getFile('history_tracker.csv', {create: true}, function(fileEntry) {
          fileEntry.createWriter(function(fileWriter) {
            var builder = new WebKitBlobBuilder();

            builder.append(history);

            var blob = builder.getBlob('text/plain');

            fileWriter.onwriteend = function() {
              window.open(fileEntry.toURL());
            };
            fileWriter.write(blob);
          }, errorHandler);
        }, errorHandler);
      }, errorHandler);
    }

    function errorHandler(e) {
      var msg = '';

      switch (e.code) {
        case FileError.QUOTA_EXCEEDED_ERR:
          msg = 'QUOTA_EXCEEDED_ERR';
          break;
            case FileError.NOT_FOUND_ERR:
          msg = 'NOT_FOUND_ERR';
          break;
            case FileError.SECURITY_ERR:
          msg = 'SECURITY_ERR';
          break;
            case FileError.INVALID_MODIFICATION_ERR:
          msg = 'INVALID_MODIFICATION_ERR';
          break;
            case FileError.INVALID_STATE_ERR:
          msg = 'INVALID_STATE_ERR';
          break;
            default:
          msg = 'Unknown Error';
          break;
                };
      }

You're using a nonstandard API: the filesystem API. It's not part of HTML5, and may not ever become standardized; right now it's just a proprietary Chrome extension to the standards.

I assume that since the function is called window.webkitRequestFileSystem(), that it isn't part of the HTML5 standard. The webkit engine is only used by a few browsers including Safari and Chrome, but not Firefox. You'll want to lookup the API offered by Firefox.

Chrome is currently the only browser to implemented the HTML5 Filesystem API. See the supported browsers note in the html5rocks article.
