1705178 - Investigate whether anchor tags with the download attribute may bypass data URI limits

Status: RESOLVED WORKSFORME

Description

[(No longer employed by Mozilla) Aaron Klotz]

This is based on a discussion that began over in bug 1668952 and then moved over to Matrix.

The question is whether we can exempt the data URI when it is a download, such as this:

<a download='{filename}' id='DownloadAnchor' 
                            href='data:application/octet-stream;base64,{base64_string}' target='_self'>Download</a>

We need to see how the download attribute affects delegate invocation, among other things.

As we suspected, download is now possible after Bug 1668952. I was able to create a a element with a 9.5mb base64-encoded URL and download it on Nightly without any problems.
