The state of binary data in the browser

>Firefox, conversely, doesn't have the canvas.toBlob() method, so if you want to convert a canvas to a Blob, you need to use canvas.toDataURL() and convert the dataURL to a Blob instead. blob-util does this under the hood.

I don't know where they are getting this. Firefox proposed[1] the toBlob() method, and implemented[2] it in Fx19.

Sorry, my bad. It's Chrome, Safari, and IE that don't have toBlob(). I'll fix the post.
