Steps to reproduce

1. Install firefox as .pkg
2. Right click any PDF file and select Open With -> Other
3. Search for Firefox in the list

Expected result

• Firefox is seen as a Recommended PDF app like Safari or Chrome

Actual result

• Firefox can't be selected

Regression range

• Will see for a regression

Additional notes

• The issue can be seen in the following attachment
• By selecting "All applications" from the Enable settingand choosing Firefox the following message will be shown "It's not known if this applicatioon can open the PDF file".

Doesn't seem to be a regression, the same behavior with Firefox 68.0.1 (first one to have .pkg installer).

Amir, can you please help prioritize this issue with the team? This seems to be a miss on mac where we are not even an optional pdf handler on the system.

Technically, this should be straightforward: bump https://searchfox.org/mozilla-central/source/browser/app/macbuild/Contents/Info.plist.in and ensure that we have the appropriate PDF icon in the icons set. (bhearsum just captured instructions about bumping those icons, IIRC.)

Yep, I wrote up instructions for updating the Firefox icon and this appears as if it should be the same -- just a different file. We'll need a new icon for each branding (official, aurora, nightly, unofficial).

And although I'm sure we'd prefer to have a PDF icon, I'll note for completion that we could just re-use the existing document.icns (which isn't file type specific) if, eg: we're having trouble getting UX resources.

Where would that icon appear? My experience is that on Finder a preview of the file gets displayed, not an extension specific icon?
If the is about the icon appearing in the "Open With..." menu then can we not re-use the icon offered for html files currently?

We elected to not change the icon for PDFs. I'm going to mark this as a duplicate of Bug 1683278.
