1845642 - <a> tag 'download' attribute value is not used when downloading files

Status: RESOLVED FIXED

(Firefox for Android :: Downloads, defect)

Description

[theoriginaljamesfranco]

Steps to reproduce:

Click a link that has the "download" attribute set to some value. For example:

<a href="/img/my-image.png" download="my-filename.png">Download</a>

The link should be for a same-origin resource, and should be served from a server that doesn't specify a filename in the Content-Disposition HTTP header (this would take precedence over the value of the attribute).

Actual results:

I'm prompted to download the file, but the proposed filename is that of the linked resource ("my-image.png" in the above example).

Expected results:

The proposed filename should be the value of the download attribute ("my-filename.png").

In Chrome Desktop / Firefox Desktop / Chrome Android , the file is downloaded as "my-filename.png".

In Fenix the file is downloaded as "my-image.png".

Based on this comment this seems like a broken web-platform feature and should be re-prioritized.

As my bug was duped to this one, I'm not sure if the issue is located into GeckoView or not, but I wanted to point that not only Fenix is affected, but Firefox Focus as well.

Thanks for the additional note, this bug will be to fix it in both Fenix and Focus, using android-components.

Hey,
I managed to make a repro here: https://download-atest.staticdomains.app/

You can also download the archive I've attached, run python3 -m http.server 8080 and load it on Fenix.

STR

• open https://download-atest.staticdomains.app
• click on the picture

Actual result

• The picture is downloaded as myw3schoolsimage.jpg

Expected result

• The picture should be downloaded as newname.jpg

I think this was solved by bug 2051418 entirely. (During the initial investigation, it looked like it might take two steps.)
