1763964 - Clicking PDF URL both opens & saves it

Status: RESOLVED DUPLICATE of bug 1738574

(Firefox :: File Handling, defect)

Description

[Franpa_999]

Attachment: Configuration for PDF files

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0

Steps to reproduce:

Do a google search for "MSY Parts" without quotes and left click the Parts.pdf search result: https://cdn.msy.com.au/Parts/PARTS.pdf

Actual results:

PDF is opened in Adobe Acrobat reader (good, I configured it to do this) but a copy of the PDF is also saved to where I specified downloads should go to (bad, why are multiple actions being performed for the file?).

Expected results:

The PDF should be opened in Adobe Acrobat and not saved to the HDD.

Problem did not occur in v97.0.2

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

If I click "cancel" when asked what to do, the correct behaviour is observed, the temporary file is deleted. When clicking the option to open the file the wrong behaviour of both opening the file and converting the temporary file to a saved file occurs.

You do understand that in order for the Adobe Acrobat reader to open the file it has to be saved to your HDD. That's simply how that software works. How is Firefox to know that file is temporary? What if you wanted to open it again tomorrow or next week?

Earlier versions of Firefox still saved the file but they did so to a different location and then you simply didn't realise it worked that way.

I suppose that's true, okay I'll be quiet and let the staff review the main report (1738574) on this change in behaviour.
