Use the native URL.createObjectURL
method more in web/firefoxcom.js
Given that `URL.createObjectURL` is assumed to always be available in MOZCENTRAL builds, note the existing usage in the file, there's no reason to depend on the PDF.js helper function `createObjectURL` at all here. Furthermore this patch also changes `DownloadManager.downloadData` to actually revoke the `blobUrl` after downloading has completed, which is similar to the existing code in `DownloadManager.download`.
