1130238 - PDF Viewer download button does not work within iframe

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[ajf]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150122214805

Steps to reproduce:

I opened a website (specifically, blackboard.com) which embedded a PDF within the page inside an iframe. I clicked the download button.


Actual results:

Nothing.


Expected results:

A "save file" box should pop up, like it normally would when clicking the button (not iframed).

It's not a big problem since I can just open the PDF in a new tab and then save it, or use the iframe options on the right-click menu, but it's a little weird. I assume it's some sort of web browser security model issue, as I gather that the PDF viewer is essentially just a normal web page.

Please provide a public example url where you see the issue.
The attached testcase with an iframe works as expected for me in Firefox35.0.1

Ooh, that works fine. I looked at blackboard's source and it uses an embed:

<embed scale="tofit" name="PDFEmbed" alt="" id="PDFEmbedID" src="/bbcswebdav/pid-841887-dt-content-rid-2221361_1/xid-2221361_1" type="application/pdf" controller="true" height="873" width="100%"></embed>

Yet modifying your sample to use the embed, it still works. And blackboard works now, too. I don't understand.

Closing unless I can reproduce and isolate it again.
