1318564 - downloads.download doesn't accept data URI

Status: NEW

(WebExtensions :: General, defect, P5)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

browser.downloads.download({ "url": "data:,", filename: "something" }); fails with following error:

> Type error for parameter options (Error processing url: Error: Access denied for URL data:,) for downloads.download.

Looks like that downloads.download don't support data URI but this is necessary when saving something in <canvas> to local file.

You can use a blob for this, for example:

let blob = URL.createObjectURL(new Blob([output.join('\n')]));
browser.downloads.download({url: blob, filename: 'something'});

Indeed, thank you for suggesting the workaround. However, I still feel it's a bug.
