Use Blob on newer firefox add-on

Question

This answer is outdated:

let { Cc, Ci, Cu, CC } = require('chrome');
const {Blob, File} = Cu.import("resource://gre/modules/Services.jsm", {});
console.log(typeof Blob);//undefined

How do I import a blob?

Answer 1

Cu.importGlobalProperties(["Blob"]);

This works from FF35 onwards. The older approach should work on FF34 and lower.
