1417835 - Ignores settings for PDF downloads (insists on pdf.js)

Status: RESOLVED INVALID

(Firefox :: PDF Viewer, defect)

Description

[Nicos Gollan]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171115002005

Steps to reproduce:

After updating to FF57, the browser opens PDF files in pdf.js even though it is disabled via pdfjs.disabled;true and "Applications" has the appropriate MIME type set to "always ask".


Actual results:

Tried to download https://d1wv0x2frmpnh.cloudfront.net/elite/website/assets/English-PlayersGuide-Latest.pdf and the browser appeared to hand and after aborting the operation, the tab title says "PDF.js"




Expected results:

The browser should have asked what to do.

PDF.js is horrible to use, produces wrong results, and is slow; I have settings in place not to use it, respect them!

I had

pdfjs.previousHandler.alwaysAskBeforeHandling;true
pdfjs.previousHandler.preferredAction;2

resetting those to "false" and 0 appears to restore proper behaviour. It's still a bug that the switch supposed to "[c]ompletely disable pdf.js as an option to preview pdfs within firefox" is ignored depending on further options within the feature.

When you have Javascript disabled, a pdf-file is not displayed within pdf.js. Then you must right click and "save as" before viewing it in an external viewer.

I haven't been able to reproduce on windows, linux, or mac and there haven't been any other reports. Closing for now.
